3 = 3 x 100
108 = 1.08 x 102
22 = 2.2 x 101
(3 x 108 x 22) = (3 x 100) x (1.08 x 102) x (2.2 x 101)
= (3 x 1.08 x 2.2) x (100 x 102 x 101)
= (7.128) x 10(0+2+1)
= 7.128 x 103

0022 is the same as 22 and in scientific notation it is: 2.2*10^1
2.2 x 10^4 Mg
7.3622 But converted to scientific notation, it would be 1.178452*1019
Rewrite the number as 22.0. Shift a decimal place left from the starting position, so the exponent for base 10 is 1. Hence, in scientific notation, we have... 2.2 x 10.
As a product of its prime factors: 22*5*72 = 980 Or as: 9.8*102 in scientific notation
