Solve the given problem. (a) By use of (ab) = ab (b # 0) and an = (a #0), show that (b) Verify the equation in part (a) by evaluating each side with a = 3.564 , b = 8.349, and n = 4. an = a n all Finally, use (ab)? = a"b" or (b #0) to rewrite the left side using a single exponent. n (b) Evaluate the left side. b n 3.564 4 ? b n Substitute. 8.349 a ? b n Evaluate. (Type an integer or decimal rounded to three decimal places as needed.)Solve the given problem. If f(x) = 3(5)", find f(2 - a). f(2 - a) = (Simplify your answer. Type exponential notation with positive exponents.)
