Describe and correct the error a student made when starting to solve the equation 8^x+3=2^2x-5 8^x+3=2^2x-5 (2^3)^x+3=2^2x-5 2^3x+3=2^2x-5 A. The student did not distribute 3in(2^3)^x+3 across x+3 B. The student should have expressed the initial rational exponent as the sum of two rational exponents C. The student should have divided both sides by 2^2 to simplify the expression. 0. The student dic not convert 8 to the correct power of 2
