Question

Please help im so confused

Answer 1

i am doing this in school and i cant tell the answer but i can walk you through on how to do this

here is how to do it

5.4x10^3 so what you are going to do is move the decimal to the right so your answer would be 5400.

same with negatives exept you will do move the decimal to the left

and question e the answer is 1 you have 10x10^-1 so you are moving the decimal to the left and you wind up with 1.0 i hope this helps if you have anymore questions then message me :)

Answer 2

A and D because the first factor is less than 10 and greater than 1, and the power of 10 is not 0

hope that helps :)
