which expression is equivalent to 100 n2 − 1? (10n)2 − (1)2 (10n2)2 − (1)2 (50n)2 − (1)2 (50n2)2 − (1)2
Wewaii [24]

You know that 100=10^2.

Use the property (ab)^2=a^2\cdot b^2 to state that

100n^2=10^2\cdot n^2=(10n)^2.

Then the expression 100n^2-1 is equivalent to

(10n)^2-1=(10n)^2-1^2.

Answer: correct choice is A.
