Which expression is equivalent to 100 n^2 -1? a) (10n)^2 -(1)^2

b) (10n^2)^2 -(1)^2

c) (50n)^2 -(1)^2

d) (50n^2)^2 -(1)^2

So we can ignore the endings because they all have to same endings. We know that 10^2 = 100 We see only 2 answers that have that a and b. But we also need to get the n to the power. So we power each number in the parenthesis by 2. Only A lets you power both 10 and n at the same time.
