How about: 2 to the power of 9 = 512
It is: 72/512 = 9/64
No.
The answer is 512. You just go 2x2x2x2x2x2x2x2x2=512
512^(1/3) = (2^9)^(1/3) = 2^(9×1/3) = 2^3 = 8. The cube root of 512 is 8.
Yes, 512 is less than 521 by 9.
2^9 = 512 9^2 = 81
2^9
512 is a good estimate: the number is easy to work with - particularly if you remember that it is 2^9.
2^(9) = 512
It is: 2^-9 = 1/512
2^9
