Step-by-step explanation:
Keep it as in power form. Note that the base is the same (8).
When the case is that the base is the same:
If multiplying, add the powers together.
If dividing, subtract the powers.
8^6 * 8^4 = 8^(6 + 4) = 8^10

To compare the two classes, the Coefficient of Variation (COV) can be used. The formula for COV is this:
C = s / x
where s is the standard deviation and x is the mean
For the first class:
C1 = 10.2 / 75.5
C1 = 0.1351 (13.51%)
For the second class:
C2 = 22.5 / 75.5
C2 = 0.2980 (29.80%)
The COV is a test of homogeneity. Looking at the values, the first class has more students having a grade closer to the average than the second class.
