`4.51`×
`10^-3`

2) .00632

Explanation:

1.Which of the following is equivalent to 0.00451?

=
`(451)/(100000)`

=
`(4.51)/(1000)`

=
`(4.51)/(10^3)`

=
`4.51`×
`10^-3`

Therefore the answer is (a)

===================================================================

Which of the following is equivalent to 6.32 x 10-*3?

In order to find the answer to this question you can just put the notation into standard form which means they will be equivalent to each other.

The exponent is negative so you move to the left:

`6.32=.00632`

=
`.00632`

Therefore 6.32*10^-3 is equivalent too (c) .00632
