Full solution

Q. Write the expression as a fraction with a positive exponent. \newline1r4\frac{1}{r^{4}}
  1. Use Property of Negative Exponents: To write the expression r−4r^{-4} with a positive exponent, we need to use the property of negative exponents which states that a−n=1ana^{-n} = \frac{1}{a^n} for any nonzero number aa and positive integer nn.
  2. Apply Property to r−4r^{-4}: Applying this property to r−4r^{-4}, we get 1r4\frac{1}{r^4}. This is the expression with a positive exponent.
