How do you simplify #7p^-2# and write it using only positive exponents?

Answer 1

We use the rule for exponents: #x^color(red)(a) = 1/x^color(red)(-a)#

#7p^-2 -> 7/p^(- - 2) -> 7/p^2#

To simplify (7p^{-2}) and write it using only positive exponents, you can move the term with a negative exponent to the denominator, and change the sign of the exponent to make it positive. So, (7p^{-2}) simplifies to (\frac{7}{p^2}).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
