Option B

is the choice equivalent to

Solution:

Step 1:

When we multiply two roots i.e. and the values are multiplied and still kept inside the root.

So × = .

Step 2:

We then multiply the values in the root.

=

Step 3;

We take the values out of the root by splitting up the value.

=

and

So =

When we take values out of the root, we replace it with the square-rooted value on the outside.

= .

Thus option B is correct

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
