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:

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