Is (–2n)^4 = –8n^4? choose the best explanation for why or why not.
a. yes; –2 times 4 makes –8, and the n becomes n^4.
b. yes; for n = 1, (-2n)^4 = -8 x 1 not equal to -8n^4
c. no; for values other than 0, (–2n)^4 = 16n^4 not equal to –8n^4.
d. no; the negative in front of the 2 means –2n^4 needs to become 1/2n^4

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
