Your answer :

You are correct. If the base is 3 and the exponent is 2, then the number is 3² = 3 × 3 = 9.

Now try this question. If b = 3 and n = 4, what does bⁿequal?

Answer :

bⁿ = 3⁴ = 3 × 3 × 3 × 3 = 81.

Go to Page 28

bⁿ = 4³ = 4 × 4 × 4 = 64.

Go to Page 33

I don’t get this “b” and “n” business.
