3] 2√5∙4√5

Response:

2√5 * 4√5 = 40

Step-by-step explanation:

There are many ways that you can solve this problem. One way is by multiplying the base numbers first, then multiply the radicals, and finally multiplying your two results.  

2√5 * 4√5

First, you can multiply 2 by 4.

2 * 4 = 8

Then, you can multiply √5 by √5.

√5 * √5 = √25 = 5

Finally, we multiply 5 by 8 to get the final answer.

5 * 8 = 40

So, 2√5 * 4√5 = 40

Sample Write the equation using slope and y-intercept in slope-intercept form, y = –275x + 3500. Then, substitute the x and y values of the point into the equation, 1850 = –275(6) + 3500. Simplify to see if both sides are equivalent. Yes, the instructor is correct because both sides are equivalent.
