square root 12x^3/5

- math.algebra -
**Corin**, Friday, October 26, 2007 at 10:00pmFirst you have to realize that:

square root 12x^3/5

and

(12x^3/5)^1/2

are equal! :-)

Taking the square root of a value is the same as taking the value to the 1/2 power

Use this rearrangement to simplify:

(12x^3/5)^1/2

Multipy the exponents...

12x^3/10

I'm pretty sure that's as far as you can go with the simplifying

Good luck! :-)

**drwls**, Saturday, October 27, 2007 at 4:04amThe answer depends upon whether you mean

[sqrt (12 x)]^3/5

or (sqrt 12) x^3/5,

or sqrt (12 x^3/5)

The way you wrote it is ambiguous. You need to use parentheses to clarify what you are taking the square root OF.

If you meant the last of these, then it is equal to (sqrt 12) * x^0.3
