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 to the third power x 17 to the 7th power = 3,282,709,384
2 to the third power times 5 to the fifth power equals 25,000
2 times 3 times 5 times X = 30X

2*103 = 2000
2 to the 3rd power equals 8, because 2 times 2 times 2 equals 8.
