Question

i have no clue ?????????????????????????????????????????????????????????????????????????????????????????????????

Answer 1

256-35 = 221, but this is supposed to be an exponent problem, so odds are you meant 256^35

which is a very large number, 2^8 = 256. 256^35 = (2^8)^35 = 2^280. that's an exact equivalent to the exact hundredth's power. No need for rounding though. 256^35 = 5.708990771 x 10^45. Round that to the nearest hundredth in scientific notation is 5.709 x 10^45
