Question

Write without negative exponets
1/4^-2

Answer 1

The rule about negative exponents is that you put the base under "1" in a fraction and the negative exponent becomes positive. For example,
`x^(-1)` becomes
`(1)/(x)`. So in your case,
`(1)/(4) ^(-2) = (1)/( (1)/(4) ^(2) ) = (1)/( (1)/(16) ) =16`
