Question

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

Answer 1

To rewrite \( 15^{-38} \) as an expression with positive exponents only, you can use the property of negative exponents, which states that

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

where \( a \) is a non-zero number and \( n \) is a positive integer.

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

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

Thus, the expression with positive exponents only is:

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