apply the property of negative integer exponents to rewrite 15 to the power of negative 38 as an expression with positive exponents only

Answer 1

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

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

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

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

Thus, the expression with positive exponents only is:

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