Question

Which expression is the simplified form of

Answer 1

6x2y2

5x2y2

6x4y4

5x4y4

Answer 2

since \(72=36\times 2\) you know \(\sqrt{73}=\sqrt{36\times 2}=\sqrt{36}\sqrt{2}=6\sqrt{2}\)

Answer 3

so forget about answers 2 and 4

Answer 4

actually none of the answers are correct
\(\sqrt{x^5}=x^2\sqrt{x}\) and \(\sqrt{y^4}=y^2\)
the correct answer would be
\[6x^2y^2\sqrt{2x}\]

Answer 5

thats the first one..
