since 2 to the third power(2x2x2)=8Then two to the third power times two to the third power(8x8) = 642x2x2 = 8
If you mean: 2^3 times 2^7 times 2^3 then it equals 8192
2 times 2 times 2 times 2 times 2 times x times x times x = 32x3

27. 1 times 2 is just 2. 3 to the third power is 3 times 3 which is 9, times 3, which is 27. If you multiply that by 1 again, it's STILL 27.
