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

Answer:

Option C - $n=2 \times 10^{16}$

Step-by-step explanation:

Given : The product of $1.3 \times 10 ^{-4}$ and a number n results in $2.6 \times 10^{12}$.

To find : The value of n

Solution :

According to question,

The product of $1.3 \times 10 ^{-4}$ and a number n results in $2.6 \times 10^{12}$.

$1.3 \times 10 ^{-4}\times n=2.6 \times 10^{12}$

$n=\frac{2.6 \times 10^{12}}{1.3 \times 10 ^{-4}}$

$n=\frac{2.6 \times 10^{12+4}}{1.3}$

$n=2\times 10^{16}$

Therefore,Option C is correct.

The value of n is $n=2 \times 10^{16}$
