Answer 1

umm cant

Answer 2

Oh ok.

Answer 3

Thanks

Answer 4

Of course you can do it without a calculator. Simply take the square root twice.

Answer 5

@LarsEighner If it's not too much trouble can you please give me an example?

Answer 6

smart peeps awesome

Answer 7

Well, this one is obvious on inspection, so I cannot demonstrate the whole method. But to take the first square root, put s decimal point over the radical sign (like long division). Now consider the first PAIR of numbers to the right of the decimal point under the radical. They are 00. So what is the square root of 00?

Answer 8

0

Answer 9

Right. So put a zero to the right of the decimal point over the radical. Now consider the next PAIR of numbers under the radical. They are 81. What is the square root of 81?

Answer 10

9

Answer 11

oh and the square root of 9 is 3. Got it. Thank you

Answer 12

Right. So write a 9 to the right of the zero over the radical sign. And you are done with the first square rool. See if you can take the root of 0.09 yourself.

Answer 13

Oh ok. Easier than I thought. Thank you, sir.
