Find the simplified product sqrt 2x^3 sqrt 18x^5

KatRina [158]

The first step to solving this is to remember the radical rules. They state that the product of roots that have the same index are equal to the root of the product. Knowing this,, the expression changes to the following:
$\sqrt{2 x^{3} X 18 x^{5} }$
Next you'll add the two exponents together and then calculate the product.
$\sqrt{36 x^{8} }$
Lastly,, calculate the square root to find your answer.
6 $x^{4}$
This means that the correct answer to your question will be 6 $x^{4}$ .
Let me know if you have any further questions

1. The number of courses the student takes this semester:

You can take 1 course, 2 courses, 3 courses, ...

Only countable values, the student cannot take 2.5 courses, for example. So discrete

3. The student's (exact) body temperature:

Can be decimal numbers, for example, 96.7 ºF. Continuous.

4. The number of siblings the student has:

Cannot be decimal.

You can have 0, 1, 2, ..., 20,... siblings

Discrete

Step-by-step explanation:

We know that Frank has 2 gardens, one with y vegetable seeds and another with 3y + 8 vegetable seeds. If we are trying to find the total amount of seeds planted, we must add the 2 gardens together:

Garden 1: y

Garden 2: 3y + 8

Garden 1 + Garden 2 = Total veggie seeds

y + 3y + 8 = Total veggie seeds

Total veggie seeds = 4y + 8
