Which of the following is the simplified form ofthe seventh root of x times the seventh root of x times the seventh root of x ?

Step-by-step explanation:

I'd assume your question is to simplify the expression

There are 2 rules of exponents we are going to use to simplify this expression:

Using RULE 1, we can write the radicals [expression with roots] into exponential form [with a fractional exponent] like this:

Now, the bases are same, , and we have 3 powers. Using RULE 2, we can add the powers like this:

This is the simplified form.

you need to give us more information since we can't answer

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
