$8r^{-3}r^2$
Learn how to solve multiply powers of same base problems step by step online. Simplify the algebraic expression 4r^(-3)*2r^2. Multiply 4 times 2. When multiplying exponents with same base we can add the exponents. Applying the property of exponents, \displaystyle a^{-n}=\frac{1}{a^n}, where n is a number. Any expression to the power of 1 is equal to that same expression.
