Question

y^-5
exponential form

Answer 1

To express \( y^{-5} \) in exponential form, it is important to recall the rule for negative exponents. The rule states that \( a^{-n} = \frac{1}{a^n} \) for any non-zero number \( a \) and positive integer \( n \).

Using this rule, the expression \( y^{-5} \) can be rewritten as:

\[
y^{-5} = \frac{1}{y^5}
\]

So the exponential form of \( y^{-5} \) is \( \frac{1}{y^5} \).
