Betty has worked out the financing of her coffee shop. She plans to use the money in a savings account for her start-up costs. The savings account was opened by her grandmother five years ago. To figure out the annual interest rate, Betty needs to evaluate the expression fifth root of x • 10^4 end root. Betty wants to simplify this expression in terms of fractional exponents, and write it in the form x^a • 10^b
