A. 6 x 10^4 - 8 x 10^2 = 60000 - 800 = 59200
B. 6 x 10^4 - 0.08 x 10^4 = 60000 - 800 = 59200
Both answers are the same, 59200. This shows that when subtracting numbers with the same base (10), we can simply subtract the coefficients and keep the base the same.
A. 6 x 10^4 - 8 x 10^2=
B. 6 x 10^4 - 0.08 x 10^4=
