Question

A square has an area of 324 𝑖𝑛^2

Answer 1

Area = side^2

They gave you the area. How would you find the length of the side?

Answer 2

^2

Answer 3

So we have the length of the side

We want to find the area

We would square the length of the side (that's what s^2 is)
And we would get the area

The question wants us to do the OPPOSITE

We have the area, but how would we find the length of the side?

What is the opposite of squaring something?
^2 is called squaring but essentially when you have something^2 it is multiplication

so
something^2 = something * something
something^3 = something * something * something

you just multiply the number by itself for 2 or 3 or whatever the exponent is

Answer 4

Oh so itd be D

Answer 5

How did you get to that?

Answer 6

Do you know what squaring is and what square roots are?

Answer 7

Sort of

Answer 8

What is

4^2

Answer 9

16

Answer 10

4*4

Answer 11

Good!

What is the squareroot of 16?

\(\Large \sqrt[2]{16}=?\)

Answer 12

4

Answer 13

Perfect! So you realize that \(\Large\sqrt[2]{x^2}\) is going to be EQUAL to x

So if we squared a number, we would take the square root of it to find out what that original number is

Answer 14

Ok

Answer 15

Have you figured out the answer now?

Answer 16

B

Answer 17

Correct!

Answer 18

Ok thank you

Answer 19

Of course, no problem!
