Question

Choose the correct simplification of the expression the quantity 4 times x all over y all to the second power.

4 times x to the second power all over y to the second power

8 times x to the second power all over y to the second power

16 times x to the second power all over y to the second power

16 times x to the second power all over y

Answer 1

@amistre64

Answer 2

\[\large (\frac{4x}{y})^2\]
Like that?

Answer 3

Yes I think the answer it either A or B but im not sure

Answer 4

Not quite...since

\[\large (\frac{4x}{y})^2 = \frac{(4x)^2}{y^2}\]

Answer 5

So I would have to do 4x times 4x and get 16x over y^2

Answer 6

So It would be C

Answer 7

And we know that 4x is actually just written as \(\large 4 \times x\)

So really we have

\[\large \frac{(4 \times x)^2}{y^2} \rightarrow \frac{(4^2 \times x^2)}{y^2}\]

Answer 8

C would be correct!

Answer 9

Thank you soo much! Can I mention you in more of these questions if I have any?

Answer 10

Of course :)

Answer 11

OK thanks!!!
