Rita said that 8^ (2 /3) = 128 because 8^ (2/ 3) = 8^2 ⋅ 8 ^(1 /3), so 8^ (2/ 3) = 64 ⋅ 2, and then 8 ^(2 /3) = 128. use properties of exponents to explain why she is or is not correct.

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

the anwser is d) 75°
