3/(42 + 2) = 3/(18) = 1/6
4^6 divided by 4^3 = 4^3 4096 divided by 64 = 64
8 divided by 2 = 4 4 to the second power (42) = 16 The square root of 16 = 4
4 to the power 4 =256
-3 divided by 43 = -0.046875
(24/8) x 22 = 3 x 4 = 12

Second step is
4x4x4=64/2=32x32=1024 or 43 divided by 22 = 64 divided by 4 = 16
