2.7 × 101 in standard form?

Question

what is this i have no idea help me

Answer 1

My advice would be to break it up and do 2.7 X 100 first. 2.7 X 100 = 270 (you can easily find this by moving the decimal to the right twice because 100 contains two zeros. Then since there is one left over, you can simply add 2.7 to 270, which is equal to 272.7.
