Question

Simplify the expression using the properties of exponents:
(3y)^-3

Answer 1

\[\frac{1}{(3y)^3}=\frac{1}{27y^3}\]\]

Answer 2

1/(27 y^3)

Answer 3

now ask your math teacher why
\[\frac{1}{27y^3}\] is "simpler" than
\[(3y)^{-3}\]

Answer 4

because frankly there is nothing "simpler" about either one. one is written in parentheses on one line with a negative exponent. the other is written as a fraction with positive exponents. they each have exactly 6 symbols by my count.
