Study the problem below, then continue.

.00006 X .144 X .02 =

Solution:

Convert the numbers to SCIENTIFIC NOTATION; multiply the numerical values

and add the exponents (powers of 10).

Thus:

.00006 X .144 X .02 = (6 X 10-5) X (1.44 X 10-1) X (2 X 10-2)

= (6 X 1.44 X 2) X 10-5+(-1) +(-2) = 17.28 X 10-8
