How do you simplify this problem?

Question

√[196x22y6z18]

Answer 1

Are there some ^ missing from this? I'm going to assume that 22 is the exponent of x rather than the coefficient for y (and similar for 6 and 18).

To take the square root of a variable raised to an exponent, you simply halve the exponent. If you have several variables multiplied together, just take them one at a time, like this:

√[196x^22y^6z^18] =

√[196] * √[x^22] * √[y^6] * √[z^18] =

16 * x^11 * y^3 * z^9 =

16x^11y^3z^9

Hope that helped! :-)

Answer 2

I want to skip long answers. It's the same as the first answerer's but root of 196 is 14 NOT 16.

Answer 3

There is a small careless mistake in the former answer. square root of 196 is 14.
