Question

Part 1: Explain, using complete sentences, how to simplify the expression below.
Part 2: What is the simplified expression?

(3x3y4)2

Answer 1

well the power of 2 operates on each part of the expression which means

\[(3x^3y^4)^2 = (3)^2 \times (x^3)^2 \times (y^4)^2\]

the index law for power of a power is multiply the powers.

\[(x^a)^b = x^{a \times b}\]

use the law to simplify your expression.

hope this helps

Answer 2

so 27x^6y^8?

Answer 3

not quite you have to evaluate

\[3^2 = \]

and its not 27

Answer 4

but the rest is great work

Answer 5

so its 9?
