Question

Please convert these values from scientific notation into long hand notation. To receive credit, plea: values over 999; use 0.# for values less than one; keep the two significant figuares. 3.3x1010 5.4x10-6 7.2x10-1 4.5x100=

Answer 1

The required answers are:

33,000,000,000

0.0000054

0.72

4.5

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)
`3.3* 10^(10)`

Here the exponent of 10 is 10 which is a positive number, so move the decimal point right as shown:

`3.3* 10^(10)=33,000,000,000`

Part (B)
`5.4* 10^(-6)`

Here the exponent of 10 is -6 which is a negative number, so move the decimal point left as shown:

`5.4* 10^(-6)=0.0000054`

Part (C)
`7.2* 10^(-1)`

Here the exponent of 10 is -1 which is a negative number, so move the decimal point left as shown:

`7.2* 10^(-1)=0.72`

Part (D)
`4.5* 10^0`

Here the exponent of 10 is 0. Use the property of exponent
`a^0=1`

`4.5* 10^0=4.5`
