Solve the given problem. n - 1 a b (a) By use of (ab) = a"b" or n (b # 0) and a n (a #0), show that a (b) Verify the equation in part (a) by evaluating each side with a = 3.228 , b=8.639, and n = 5. n a n a (a) First, use (ab)? = a"b" or bn (b # 0) to rewrite the left side using negative exponents. n (Do not simplify.) a
