Ineed a lot of with practice problems, i am not understanding math right now. will give

if you know how to do any of these it will be much appreciated. you do not have to answer every single one if you do not know them.

1. what is the simplest form of the radical expression? show all work.

3^3sqrt21 - 6^3sqrt2a

(the ^3's are attached to the sqrt, not the 3 and 6.)

2. simplify. show all work.

3^1/2 x 3^1/2

3. rewrite ^nsqrtx^m using a rational expression. show all work.

4. sqrt250x^16/sqrt2x show all work

5. what is the solution of the equation? show all work.

sqrt2x+13 - 5 = x

6. what is the solution of the equation? show all work.

3 ^5sqrt(x+2)^3 + 3 = 27

(^5 is connected to sqrt.)

The expression is

We need to solve each power: .

The Greatest common factor between 27 and 216 is 27, so we extract that

, which is the simplest form.

The expression is

Notice that bases are equal, that means we need to sum exponents only to find the simplest form

The expression is

Here we transform the root into a fractional exponent.

The expression is

Here we need to express it as the root of a fraction

Then, we divide

The equation is

First, we move the term 5 to other side, then we elevate the equality to the square power to eliminate the square root. Consequently, we have to solve the square power of the binomial x+5:

Then, we move all terms to one side

Now, we have to find to numbers which product is 12 and which sum is 8, those numbers are 6 and 2:

The solutions are -6 and -2.

The expression is

First, we subtract the equation by 3, then we divide by 3:

Then, we elevate each side to the fifth power to eliminate the root

Now, we apply a cubic root to each side
