(5.5 × 10^-6) - (3.7 × 10^-7)
A.
1.8 × 10^-6
B.
1.8 × 10^-7
C.
5.463 × 10^-6
D.
5.13 × 10^-6

Answer 1

The answer is
0.000005

Answer 2

Option D.

Explanation:

The given expression is
`(5.5* 10^(-6))-(3.7* 10^(-7) )`

We have to write it in the simplified form.

`(5.5* 10^(-6))-(3.7* 10^(-7) )`

=
`(5.5* 10^(-6))-(0.37* 10^(-6) )`

= (5.5 - 0.37)×
`10^(-6)`

= 5.13×
`10^(-6)`

Option D will be the answer.
