Question

What is 1 x 102 divided by 1 x 10-3?
O 1x 10-6
O 1x 10-1
0 1x 103
O 1 x 105

Answer 1

Option (d) is correct.

Step-by-step explanation:

Let
`x=10^2` and
`y=10^(-3)`.

We need to find the value of
`(x)/(y)`.

Put the values of x and y such that,

`(x)/(y)=(10^2)/(10^(-3))\\\\=10^2* 10^3\ (As\ (1)/(x^(-a))=x^a)\\\\=10^5\ (As\ x^a* x^b=x^(ab))\\\\=1* 10^5`

So, the required answer is equal to
`1* 10^5`. Hence, the correct option is (d).
