- Write each expression as a multiple of a power of 10:
a. 0.04
b. 0.072
c. 0.0000325
d. Three thousandths
e. 23 hundredths
f. 729 thousandths
g. 41 millionths

To write the expression as a multiple of a power of 10 ; we express the decimals in scientific notation :

0.04 :

0.04 =

0.072 :

0.072 =

0.0000325 :

0.04 =

Three thousandth = 0.003 :

0.003 =

23 hundredths = 0.023:

0.023 =

729 thousandths = 0.00729 :

0.00729 =

41 millionths = 0.0000041

0.0000041 =

Hence, the scientific representation.

To write the following expressions as a multiple of a power of 10 you need to take each of the numbers and raise them to the power of 10.

An easy way to do this is to find the decimal point and move it over one spot to the right.

a. 0.04- move the decimal one to the right and you get that 0.04^10=00.4.

b. 0.072-move the decimal to the right one spot you get 0.072^10=00.72.

c. 0.0000325-move your decical to get 0.0000325^10=00.000325.

d. 0.003-move the decimal to get 0.003^10=00.03 or three hundredths.

e. 0.23-move your decimal to get 0.23^10=2.3 or two and three tenths.

f. 0.729-move you decimal to the right to get 0.729^10=07.29 or seven and twenty-nine hundredths.

g. 0.000041- move your decimal to the right to get 0.000041^10=00.00041 or forty-one hundred thousandths.
