1) (4y)^3 for y=1/2

(4*1/2)^3 = 2^3 = 8

2) 3(5 – 2m /4) for m=2

3(5-2*2/4) = 3(5-1) = 12

3)[ (L + 1.9 ) -3]8 for L =6.2

[(6.2 +1.9) -3]8 = [8.1-3]8 = 5.1*8 = 40.8

4)a + 6b for a =1.2,b=0.6

1.2 +6*.6 = 1.2 + 3.6 = 4.8

5) ( c+ 3) d for c = 1.5, d= 10

(1.5 +3)*10 = 4.5*10 = 45

Just put the numbers in place of the letters.
