Apply the Property of Negative Integer Exponents to rewrite 15^−38

Question

as an expression with positive exponents only.

Answer 1

To rewrite \( 15^{-38} \) using positive exponents, you can use the property of negative integer exponents, which states that:

\[ a^{-n} = \frac{1}{a^n} \]

So, applying this rule to \( 15^{-38} \):

\[ 15^{-38} = \frac{1}{15^{38}} \]

Thus, the expression with positive exponents only is:

\[ \frac{1}{15^{38}} \]
