106 x 102 = 10(6+2) = 108
6.12*102 = 612
The result is 4 x 1018 or 4,000,000,000,000,000,000
36 times 10^3 plus fifteen times 10^2 is equal to 37,500.
9001 x 102 = 900100.
(4 x 10 )3 = 64,000 4 x 103 = 4000. It depends if the question is 4 times -----10 to the third power or 4 times ten ----- to the third power.
It can also be expresses as 4x10x10x10x10x10 which equals 400,000.
