What is the square root of 5.206 times 10 to the seventh to the nearest hundredth?

00:11

Here are your options...

00:17

Okay, so we need to figure out the value of the

00:19

square root of a number to the closest hundredth.

00:22

Let's repeat the most important part of that... it'll save us a whole lot of work.

00:27

TO THE CLOSEST HUNDREDTH.

00:29

One more time, with feeling... TO THE CLOSEST HUNDREDTH

00:35

Only one of the answers is a number that includes the right number of

00:39

numbers after the decimal point... to the hundredths place.

00:46

Now, if we can remember what the hundredths place is,

00:48

we can answer this question in a snap.

00:53

If not, we'll tell you just this once. You're on your own for the test, though.

00:57

01:08

So which of the answer choices has two numbers after the decimal point?

01:11

Option D, 7215.26.

01:15

Saves us a lot of time punching numbers on our calculator, doesn't it?
