Apply the Property of Negative Integer Exponents to rewrite 15^−38 as an expression with positive exponents only

Answer 1

To rewrite \( 15^{-38} \) with positive exponents only, we can apply the property of negative integer exponents. The property states that:

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

Applying this property to \( 15^{-38} \):

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

Therefore, the expression with positive exponents only is:

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