An exponent tells how many times the base is used as a factor. 10^3 = 10 x 10 x 10
104
10 times 1000

An exponent tells how many times to multiply a number by it self. In this table, the symbol ^ indicates the exponent - (In case the symbol came through garbled, it is the shifted 6) 10 ^5 = 100000 10 ^4 = 10000 10 ^3 = 1000 10 ^2 = 100 10 ^1 - 10 Following that logic - 10 ^0 = 1 10 ^-1 = .1 10 ^-2 = .01 So: 3 x 10 ^-2 = .03 - wjs1632 -
1.0 × 104
100,000,000,000.
10⁻⁴ = 1/10⁴= 1/10000 Then 8.73 x 10⁻⁴= 8.73/10000 = 0.000873
