Negative Integer Exponents Practice

Math 8 Q1 (Pre-Algebra) / Exponent Rules

Apply the Property of Negative Integer Exponents to rewrite 15^-38 as an expression with positive exponents only. (1 point)

1 answer

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 to \( 15^{-38} \):

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

So, the expression with positive exponents only is:

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