Question

What is the correct way to express a⁻² with a positive exponent?

Answer 1

`1/(a^2)`

Explanation:

Whenever there's a negative value in the exponent... it means.... inverse it
`2^(-2)=2^(-2)/1=1/(2^2)`
It is taken like that because you can take it as one big inverse proportion or something....
`10^2=10xx10`
`10^1=10`
`10^0=10/10=1`
`10^-1=10/100=1/10`
You see?.... Hope you understood it well
