Square Root Expressions, a la Shmoop. For the entire summer, you've interned at

00:09

Water Wars.

00:10

You've been bombarded by water balloons. Sprayed by high-pressure hoses. Dunked in every dunk

00:16

tank.

00:21

Now it's time for the end-of-season staff party.

00:23

Your boss brings out a top-secret water gun that will be unveiled next year.

00:30

Whichever staff member can guess how much water it holds wins the coveted Golden Squirt

00:34

Gun trophy.

00:36

They've given everyone the top secret formula: two square root of… x to the power of two

00:42

plus y. As an intern, people talk about all sorts

00:45

of things around you, not realizing you're listening.

00:48

At the water cooler... which is a dunk tank filled with ice water... you overheard two

00:53

executives say that x is two and y is three. Now that you know x is two and y is three,

01:07

you've got this golden squirt gun in the bag. The equation now looks like this...

01:12

two square root of… two squared plus three. We'll take care of the exponent first.

01:22

Two to the power of two, or two squared, is also two times two, which is four.

01:29

Since four plus three is in parentheses, we need to handle that next.

01:34

Even in the dunk tank, we can figure out that four plus three equals seven.

01:39

So the answer is two square root of seven. You win the coveted Golden Squirt Gun!

01:46

It almost makes all the water-torture

02:01

worth it.

02:06

Almost.
