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.

b

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
