115 scientific notation

Answer 1

All you need to do for scientific notation is move the decimal point until the most significant digit (farthest to the left digit) is in the one's place. Count how many places you moved the decimal point, and this is your 'e' number. All 'e' shows is the exponent you need to multiply 10 by to get the original number. Our answer, 1.15e2, which really means 1.15 x 102
