Question

Write expression using a positive exponent

Answer 1

$a^{-n}=\dfrac{1}{a^n}\\\\4^{-1}=\dfrac{1}{4}\\\\5^{-3}=\dfrac{1}{5^3}\\\\-6^{-2}=-\dfrac{1}{6^2}\\\\-3^{-3}=-\dfrac{1}{3^3}\\\\3^{-5}=\dfrac{1}{3^5}\\\\10^{-4}=\dfrac{1}{10^4}\\\\p^{-1}=\dfrac{1}{p^1}\\\\a^{-10}=\dfrac{1}{a^{10}}\\\\d^{-3}=\dfrac{1}{d^3}\\\\q^{-4}=\dfrac{1}{q^4}\\\\b^{-15}=\dfrac{1}{b^{15}}\\\\r^{-20}=\dfrac{1}{r^{20}}$
