Is the cubed root of 27 a whole number?

Answer 1

YES!!!!

It is '3'

Remember .

3 x 3 x 3 = 9 x 3 = 3^(3) = 27

The inverse of this function is taking the roots.

Since we have 3^(3) = 27

Then cube rooting

3 = cu.rt(27) = 27^(1/3)

NB You can increas a number to the power 'n'.

To find the 'root'; it is the 'n th' root.

e.g.

x^(n) = z

Then

x = n th.rt(z) = z^(1/n) .

Answer 2

yes, it is 3
