A. 6 x 10^4 - 8 x 10^2=

B. 6 x 10^4 - 0.08 x 10^4=

what do you notice between the two answers?

1 answer

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.
