2. Evaluate the expression. Show your work. 2a^{4} - 3b^{3}
if a = -2 and b = 3



please help

Respuesta :

first round 4 were helped then 4*4 , then 4^3  and so on .
so during the sixth round 4^6 friends were helped

4^6 =  4096

2.   = 2(-2)^4 - 3(3)^3
       = 2 * 16 - 3*27
  =  32 - 54
  =   22
