Question

Jamal simplified the expression startroot 75 x superscript 5 baseline y superscript 8 baseline endroot where x greater-than-or-equal-to 0 and y greater-than-or-equal-to 0. startroot 75 x superscript 5 baseline y superscript 8 baseline endroot = startroot 25 times 3 times x superscript 4 baseline times x times y superscript 8 baseline endroot = 5 x squared y squared startroot 3 x endroot which describes the error jamal made?

Answer 1

The statement that describes the error that Jamal has made is option A: He should have written the square root of y Superscript 8 in the answer as y Superscript 4, not y squared.

What is the expression about?

An expression is often seen as a form of mathematical statement about a thing.

Note that from the expression:

$\sqrt{75x^{5} y^{8} }$

$\sqrt{25 x 3 x x^{4} x x x y^{8} }$

=   5x² y² $\sqrt{3x}$

So, The statement that describes the error that Jamal has made is option A: He should have written the square root of y Superscript 8 in the answer as y Superscript 4, not y squared.

See options below

Which describes the error Jamal made?

A. He should have written the square root of y Superscript 8 in the answer as y Superscript 4, not y squared.

B. He should have written the square root of x Superscript 4 in the answer as x, not x squared.

C. He should have written the 5 inside of the radical in the answer.

D. He should have written the 3 outside of the radical in the answer.
