8 x 8 x 8 = 512
The cube root of 512 is 8
512. 8X8X8=512 Or 8^3=512
Not easy to do in your head. 210 = 1024, 29=512, so 229 will be 1024 * 1024 * 512. REALLY rough estimate is 1000 * 1000 * 500 = 5 with 8 zeros. 500,000,000. My TI-84 Silver Edition tells me it is really 536,870,912.
512 is a good estimate: the number is easy to work with - particularly if you remember that it is 2^9.
396+512=908 Not clear what the point of the question was, you may want to adjust it.
The best estimate is the true value.512 = 2^9 = 2^7*2^2 = 128*4Then 512*25 = (128*4)*25 = 128*(4*25) = 128*100 = 12800.
It is: 512 because 1*512 = 512 and 16*32 = 512
55% of 512= 55% * 512= 0.55 * 512= 281.6
x -512 = 0 Add 512 to both sides of the equation. x = 512
512 = 29 512 x 512 = 262144 = 218
512
8 x 8 x 8 = 512
It is: 1/512 times 512 = 1 or 512 to the power of 0 = 1
512 = 1536
512 - 320 = 192
