Question

The product of 1.3x10^-4 and a number n results in 2.6 x 10^12. what is the value of n?

Answer 1

The correct answer is n = 2 * 10 ¹⁶

Explanation:

Let's find the value of n, this way:

1.3 x 10⁻⁴ * n = 2.6 x 10¹²

n = 2.6 x 10¹² / 1.3 x 10⁻⁴

n = (2.6 / 1.3) * (10¹² / 10⁻⁴)

n = 2 * 10¹² ⁺ ⁴

n = 2 * 10 ¹⁶

Answer 2

Answer:2×10^16

Step-by-step explanation: 1.3×10^-4×n=2.6××10^12

n=2.6×10^12/1.3×10^-4

n=2×10^12+4

n=2×10^16
