3^4 or 9^2
In infinitely many ways. However, if you want powers of positive integers only, then you can express 64 as a power of 2, 4, 8 and of 64 itself.
2^6, 4^3, 8^2
It belongs to the set consisting of -64, the set consisting of minus (powers of 2), the set of minus (multiples of 2), the set {2, 3.78, sqrt(99), -64} In fact, it belongs to any set that contains it. And there are infinitely many such sets.
You could write a fraction as a proper, improper or mixed fraction.
3^4 or 9^2
One way is 4 the power of 2
8000 is:20380001 (that's all that i could find)
In infinitely many ways. However, if you want powers of positive integers only, then you can express 64 as a power of 2, 4, 8 and of 64 itself.
There are three ways: Either 27 raised to the power of 2 or 9 raised to the power of 3 or 3 raised to the power of 6
81 = 9^2 = 3^4 ("^" means "to the power of" - ^2 = squared, ^3 = cubed, etc.)
25 to the 2nd power, 5 to the 4th
16 = (256)1/2 Also, 16 = (64)2/3 . There are an infinite number of 'correct' answers to this question as it is posed. To limit the number of good answers to 3, insert 'integral' before 'powers'. To limit to 2 only, you need to disqualify (16)1 . Yes, this is picky-picky, but mathematics is all about precision and absolute certainty. 16 = (2)4 16 = (4)2
2 ways
20/100 or 2/10
