Question

The product of 1.3 times 10 ^ -4 and a number n results in 2.6 times 10 ^ 12. What is the value of n?

A. 2 x 10^-8
B. 2 x 10^-3
C. 2 x 10^16
D. 2 x 10^48

Answer 1

n would equal = 20,000,000,000,000,000 or 2.0×10^16

Answer 2

Option C -
`n=2 * 10^(16)`

Explanation:

Given : The product of
`1.3 * 10 ^(-4)` and a number n results in
`2.6 * 10^(12)`.

To find : The value of n

Solution :

According to question,

The product of
`1.3 * 10 ^(-4)` and a number n results in
`2.6 * 10^(12)`.

`1.3 * 10 ^(-4)* n=2.6 * 10^(12)`

`n=(2.6 * 10^(12))/(1.3 * 10 ^(-4))`

`n=(2.6 * 10^(12+4))/(1.3)`

`n=2* 10^(16)`

Therefore,Option C is correct.

The value of n is
`n=2 * 10^(16)`
