Question

If n is a positive integer and k = 5.1 10n, what is the value of k ?

Answer 1

Step-by-step explanation:

We are given that n is a positive integer and k = 5.1*10^n and need to determine k. We see that if n = 4, then k = 5.1 x 10^ 4 = 51,000, which is between 6,000 and 500,000, If n = 3, then k = 5.1 x 10^3 = 5,100, which is less than 6,000 and if n = 5, then k = 5.1 x 10^5 = 510,000, which is greater than 500,000.
