Your boss brings out a top-secret water gun that will be unveiled next year.
Whichever staff member can guess how much water it holds wins the coveted Golden Squirt
They've given everyone the top secret formula: two square root of… x to the power of two
plus y. As an intern, people talk about all sorts
of things around you, not realizing you're listening.
At the water cooler... which is a dunk tank filled with ice water... you overheard two
executives say that x is two and y is three. Now that you know x is two and y is three,
you've got this golden squirt gun in the bag. The equation now looks like this...
two square root of… two squared plus three. We'll take care of the exponent first.
Two to the power of two, or two squared, is also two times two, which is four.
Since four plus three is in parentheses, we need to handle that next.
Even in the dunk tank, we can figure out that four plus three equals seven.
So the answer is two square root of seven. You win the coveted Golden Squirt Gun!
It almost makes all the water-torture
