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 only positive exponents, we can use the property of negative integer exponents, which states that:

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

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

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

Thus, the expression \( 15^{-38} \) can be rewritten as \( \frac{1}{15^{38}} \), which has positive exponents only.
