Question

what is the square root of 49 multiplied by the square root of 9

Answer 1

First we need to find the the answer to both the square root of 49 and 9.

The "square root" is a term referring to a number, multiplied by itself (x • x) would be = to your square root.

So for example: Square root of 16 = 4 because 4*4=16 

So lets get out numbers:

$\sqrt{9} =3$
$\sqrt{49}=7$

Now you multiply 3*7 (or 7*3) and you get 21.

Final answer: 21

Answer 2

Well, first, you need to find the square root of the two numbers. To find it, they are the numbers multiplied by each other to get a product.  Example: The square root of 49 = 7. Why? Because 7 times 7 = 49. You see how we multiplied 7 by its own self, and how we DIDN'T multiply 7 by any other number BUT itself? See, that's how you find the square root. So, we know that 3 times 3 = 9, and THAT means the square root of 9 = 3. All we have to do now is solve the problem when it says to multiply both of the numbers, (7 times 3), and WHAT DO YOU GET? 21! (Get it? Like the 21 joke-trend?) :D (Laughing emote). :P
Final Answer: 21. :-)
