Question

what is the cube root of 64? how do you work it?

Answer 1

64=2^6
or 64=4^3

Hope this helps

Answer 2

How do did you get that?
also it helps heaps thanks :)

Answer 3

Well over 18 years of maths study helps :)
The powers of 2 I know even if I just wake up from my afternoon nap

Answer 4

factor out 64

64 = 8(8) = 2(4)(2)(4) = 4(4)(4)

so, cube root of 64 = cube root of [4(4)(4)] = 4

hope this helps

Answer 5

factor out 64

64 = 8(8) = 2(4)(2)(4) = 4(4)(4)

so, cube root of 64 = cube root of [4(4)(4)] = 4

then
64=(4)^3

=> cube root 64=4

hope this helps

Answer 6

The proper way to do this question if you do not know that 64=2^6 is
What are the divisors of 64.
It is an even number so 2 is
64/2=32
32 is even
32/2=16
.....
16/2=8
8/2=4
4/2=2
2/2=1

How many times did I do that 32,16,8,4,2,1 6 times
So 64=2^6
6=2*3
64=2^(2*3)=4^3

Answer 7

Thank yous so much. If you put down 2^6 would it matter, or do you have to find a number that is only multiplied 3 times..4x4x4 since its cube?

Answer 8

The answer is 4: as the question asks for the cube root
