Question

the product of 1.3x10^-4 and a number n results in 2.6x10^12. What idle the value of n

Answer 1

1.3 x 10^-4 * n = 2.6 x 10^12
n = 2.6 x 10^12 / 1.3 x 10^-4
n = (2.6 / 1.3) x 10^16
n = 2 x 10^16

Answer
Idle the value of n = 2 x 10^16

Answer 2

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

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

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

$n = 2 \times 10^{12 - (-4)}$

$n = 2 \times 10^{12 + 4}$

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

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