simplify the radical and use the imaginary unit i.
Answer:
√
−
49
=
7
i
Explanation:
A square root of a number
n
is a number
x
such that
x
2
=
n
Note that if
x
is a Real number then
x
2
≥
0
.
So any square root of
−
49
is not a Real number.
In order to be able to take square roots of negative numbers, we need Complex numbers.
That's where the mysterious number
i
comes into play. This is called the imaginary unit and has the property:
i
2
=
−
1
So
i
is a square root of
−
1
. Note that
−
i
is also a square root of
−
1
, since:
(
−
i
)
2
=
(
−
1
⋅
i
)
2
=
(
−
1
)
2
⋅
i
2
=
1
⋅
(
−
1
)
=
−
1
Then we find:
(
7
i
)
2
=
7
2
⋅
i
2
=
49
⋅
(
−
1
)
=
−
49
So
7
i
is a square root of
−
49
. Note that
−
7
i
is also a square root of
−
49
.
What do we mean by the square root of
−
49
For positive values of
n
, the square root is usually taken to mean the principal square root
√
n
, which is the positive one.
For negative values of
n
, the square roots are both multiples of
i
, so neither positive nor negative, but we can define:
√
n
=
i
√
−
n
With this definition, the principal square root of
−
49
is:
√
−
49
=
i
√
49
=

i
Footnote
The question remains: Where does
i
come from?
It is possible to define Complex numbers formally, as pairs of Real numbers with rules for arithmetic like this:
(
a
,
b
)
+
(
c
,
d
)
=
(
a
+
c
,
b
+
d
)
(
a
,
b
)
⋅
(
c
,
d
)
=
(
a
c
−
b
d
,
a
b
+
c
d
)
These rules for addition and multiplication work as expected with commutativity, distributivity, etc.
Then Real numbers are just Complex numbers of the form
(
a
,
0
)
and we find:
(
0
,
1
)
⋅
(
0
,
1
)
=
(
−
1
,
0
)
That is
(
0
,
1
)
is a square root of
(
−
1
,
0
)
Then we can define
i
=
(
0
,
1
)
and:
(
a
,
b
)
=
a
(
1
,
0
)
+
b
(
0
,
1
)
=
a
+
b

Answer:
Ima guess 60
Step-by-step explanation:
9514 1404 393
Answer:
60°
Step-by-step explanation:
The exterior angle is equal to the sum of the remote interior angles:
100° = 40° +∠B
60° = ∠B . . . . . . . . . . . . . subtract 40° from both sides
Work out the value of x. And give a reason for your answer
Answer:
x = 120°
The triangle is an equilateral triangle and all the angles in an equilateral triangle equal 60°.
Straight lines have 180° angles.
180 - 60 = 120
Choose an even number between 10 and 19 . Draw a picture and then write a sentence to explain why it its an even number
Answer:
12, 14, 16, and 18 are all even numbers between 10 and 19
Step-by-step explanation:
They are all even numbers because they end in 2, 4, 6, or 8. 0 is considered neither even nor odd.
Answer:
12 is an even number because it is divisible by 2

1/4X - 8 + 12 = -3/4X + 5 Solve for X
Answer:
x = 1
Step-by-step explanation:
I'm going to convert this to decimal to make it easier to type
Since x = 1, there is no need to include it in the equation
1/4 - 8 = -7.75 + 12 = 4.25
-0.75 + 5 = 4.25
Answer:
By simplifying both sides of the equation, then isolating the variable.
X=1
Step-by-step explanation:
1/4*1-8+12=-3/4*1+5

-5 + 9x4-2+(8-3)x6 divide 2 +3
It's a fraction. At the numerator we have : -5+9×4-2+(8-3)×6 = -5 + 36 -2 + 5×6 = -5 +36-2 +30= 31-2+30 = 29+30= 59
59/2 = 29.5 +3 = 32.5
Write an equation for a line parallel to y = − 2 x + 4 and passing through the point ( 2 , 1 )
Answer:
x=2y
Step-by-step explanation:
y=-2x+4 is perpendicular to the line which passes through (2,1). We know that we can use the formula y=mx+c to find the gradient of the line with the equation y=-2x+4, which will give you -2. The product of the gradient of two perpendicular lines is always -1. So the gradient of the line which passes through (2,1 ) is -½.
Now,to find the equation of the line,we use the formula y-y1=m(x–x1)which will give you the answer 2y=x when solved.

Is the function y=|x-5|a one to one function? Justify your answer
Answer:
no
Step-by-step explanation:
if a=0 it's y=0, it's not one to one
if ais not 0, it's a even function and it's not 1 to 1, for example a=1, x=8 and x=2 have same f(x)
Find the value of x in the isosceles triangle shown below.
Answer:
Step-by-step explanation:
ΔABD ≅ ΔACD {A S A congreunt}
∠ADB ≅ ∠ADC {CPCT}
∠ADB + ∠ADC = 180 {linear pair}
2∠ADB = 180
∠ADB = 180/2
∠ADB = 90
∠ADB = ∠ADC = 90.
So, now we can use Pythagorean theorem to find x
x² = 8² - 2²
= 64 - 4 = 60
x = √60

1.3 x 9.16? Multiplying decimals
One option (that I would use):
Ignore the decimals and multiply 13 x 916.
9 1 6
x 1 3
2 7 4 8
9 1 6 0
1 1 9 0 8
OK, now take into account there were a total of three digits to the right of decimal points (3, 1, and 6), so your answer also needs three digits to the right of your decimal point.
