Question

I got the numbers right, but not the correct powers.

a) 445.5 X 10⁴ I got 4.455 X 10 to the? It is not 4 and it is not 2

b) 7804.7 X 10^-6 I got 7.8047 X 10 to the? It is not -6 and it is not 3

c) 0.013 X 10^-8 I got 1.3 X 10 to the? It is not -8 and it is not -2

Answer 1

a) 445.5x10⁴ = 44.55x10⁵ = 4.355x10⁶

b) 7804.7 X 10^-6 = 780.47x10^-5 = 78.047x10^-4 = 7.8047x10^-3

See if you can get (c)
