The square root of 9 is 3. If s is the square root of a number, n, then sxs=n. In other words, the square root of n is just asking, find a number that you can multiply by itself and obtain n. The concept can be generalized to cube roots, where we say find a number multiplied by itself 3 times.
The square root of a perfect square and the cube root of a perfect cube is always an integer. A perfect square is a number multiplied by itself. A perfect cube is a number multiplied by itself twice. Example: 3 x 3 is 9, the square of 3 3 x 3 x 3 is 27, the cube of 3
729 = 9 x 9 x 9. So the cube root is 9
The cube root of 2/9 is 0.606 approx.
No, the cube root of -9 is an irrational number.
The cube root of 729 is 9 and 9 squared is 81.
9
9 and 81.
The square root of 81 is 9, and 9 cubed is 729.
Oh, dude, you're hitting me with some math now? Alright, so the square root of 81 is 9, and if you cube that, you get 729. Boom, math wizardry in action! Like, who needs a calculator when you have me, right?
The square root of 9 is the number you times by itself to get 9, so that's 3. Then to cube it you do 3 x 3 x 3 which is 27.
8.056... (3 d.p.)
5.76899828 orFactor the 192:=8x24=8 x 8 x 3remember that cube root of 8 is 2, so you have:2 x 2 (cube root of 3) = 4 cube root of 3for the x^9, cube root is x^(9/3) = x^3final answer:4x^3(cube root 3)that's' it! ;)
8 is a perfect cube; it is not a perfect square. Its square root is a fraction and the square root of a perfect square is always an integer....you're thinking of 9...
