Question

Simplify completely

Answer 1

Heres the problem

Answer 2

so... what did you get?

Answer 3

B. but I'm not sure if it's right

Answer 4

well.. how did you get B?

Answer 5

Square root of 27=729
Square root of 12=144
Square root of 16=256

So I subtracted all of them and got 329.

Then I just added 4 onto the end

Answer 6

\(\bf 27^2=729\qquad \sqrt{27}\ne 27^2
\\ \quad \\
12^2=144\qquad \sqrt{12}\ne 12^2
\\ \quad \\
16^2=256\qquad \sqrt{16}\ne 16^2\)

Answer 7

say for example... can you tell what's \(\bf \sqrt{9}?\)

Answer 8

I'm still not getting it

Answer 9

81

Answer 10

Square root is opposite of square.

For example, \(\Large 3^2 = 9 \rightarrow \sqrt{9} = 3\)

Answer 11

\(\bf 9^2=81\qquad \sqrt{9}\ne 9^2\)

Answer 12

have you covered square roots yet?

Answer 13

Not really

Answer 14

well... then this exercise may not apply to you
you may want to cover that section first
