Convert the following numbers into standard notation: 12) 8.65 x 10-1 13) 9.11 x 103 14) 5.40 x 101 15) 1.76 x 100 16) 7.4 x 10-5

You need to learn to write exponents. In plain text, the preferred indicator is the caret (^), as in 8.65*10^-1. An asterisk (or raised dot (·) or times symbol (×)) is used to signify multiplication, so it is not confused with the variable x.

12) 8.65*10^-1 = 0.865
13) 9.11*10^3 = 9110
14) 5.40*10^1 = 54.0
15) 1.76*10^0 = 1.76
16) 7.4*10^-5 = 0.000074
