•Evaluaate the following using a=4 b=2 and c=3
1)a+b
2)3a+20
3)-abc-2ac
4)11ab²c-2ac
5)a2-2bc

Sagot :

1)  4 + 2 = 6
2)  3(4) + 20 = 12 + 20 = 32
3)  -(4)(2)(3) - 2 (4)(3) = -24 - 24 = -48
4) 11(4)(2)² (3) - 2 (4)(3) =  (44) (4)(3) - 24 = 528 - 24 = 504

5) a² - 2bc = (4)² - 2 (2)(3) = 16 - 12 = 4
