Question

a4(a-1)(a3) (#'s are exponents)..

A. a7
B. a6
C. a-12

Answer 1

he exponents.
So #1 is 3^-3 m^-4 t^11
or like you said, t^11 / (3^3 m^4)

#2: 2.7 ÷ 9 = 0.3 so 0.3 (10 ^ -4) = 0.00003

# just becomes c / (a^4b^2)
4 is 4^3 m^6 n^-12 or 64m^6 / n^12

Then on the other, continue by grouping:
a^3 + a^2 = a^2(a + 1)
-a - 1 = -1(a + 1)
so that part becomes (a + 1)(a^2 - 1) which then becomes (a + 1)(a + 1)(a - 1)
so the final factored form is 7(a + 1)(a + 1)(a - 1)
