Question

1/2^2/a^2 somehow equals a^2/2^2, I know this, but how? Can someone please explain this?

Answer 1

Please I'm not looking for answers just help

Answer 2

you need parentheses

1 / (2^2 / a^2) = a^2 / 2^2

but
1 / 2^2 / a^2 = 1/(2^2* a^2)

by order of operations

Answer 3

division = multiplication by reciprocal. simplify the denominator:
\(\huge \frac{1}{\frac{\color{red}{2^2}}{\color{red}{a^2}}}=\frac{1}{}*\frac{a^2}{2^2}\)
