The required answers are:
33,000,000,000
0.0000054
0.72
4.5
Step-by-step explanation:
Consider the provided information.
We can convert the scientific notation into long hand notation as shown:
If the exponent of 10 is a positive number then move the decimal point right as much as the exponent value.
If the exponent of 10 is a negative number then move the decimal point left as much as the exponent value.
Part (A) [tex]3.3\times 10^{10}[/tex]
Here the exponent of 10 is 10 which is a positive number, so move the decimal point right as shown:
[tex]3.3\times 10^{10}=33,000,000,000[/tex]
Part (B) [tex]5.4\times 10^{-6}[/tex]
Here the exponent of 10 is -6 which is a negative number, so move the decimal point left as shown:
[tex]5.4\times 10^{-6}=0.0000054[/tex]
Part (C) [tex]7.2\times 10^{-1}[/tex]
Here the exponent of 10 is -1 which is a negative number, so move the decimal point left as shown:
[tex]7.2\times 10^{-1}=0.72[/tex]
Part (D) [tex]4.5\times 10^0[/tex]
Here the exponent of 10 is 0. Use the property of exponent [tex]a^0=1[/tex]
[tex]4.5\times 10^0=4.5[/tex]
