Apply the properties 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 positive exponents only, we can use the property of negative exponents, which states that \( a^{-n} = \frac{1}{a^n} \).

Applying this property, we have:

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

So, the expression \( 15^{-38} \) rewritten with positive exponents only is:

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