Question

My teacher said 10 the the 6th power divided my 2to the 8th power times 5 to the 8th power equals 0.4to the 7th power how is that? I'm thinking maybe I copied down the wrong answer but not sure

Answer 1

10^6 = 1,000,000
2^8 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 = 256
5^8 = 5 * 5 * 5 * 5 * 5 * 5 * 5 * 5 = 390,625
1,000,000/256 * 390,625 = 1525878906.25

0.4^7 = 0.0016384

So, I think you copied it incorrectly.
