Question

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

2 times 10 Superscript negative 8
2 times 10 Superscript negative 3
2 times 10 Superscript 16
2 times 10 Superscript 48

Answer 1

2 x 10^16

Answer 2

2 x 10^16

Explanation:

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

Divide both sides by the coefficient of n.

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

The answer can be found by doing two calculations:

Divide 2.6 by 1.3 to get 2.

For the powers of 10, divide
`10^(12)` by
`10^(-4)` by subtracting exponents.

12 - (-4) = 12 + 4 = 16.

The answer is

`n=2* 10^(16)`
