You can put this solution on YOUR website! You probably already know  and  . So, since  ,  ∴  and your answer is "7 and 8."
Check:
Square root problems are set up similar to long division problems so they shouldn't be entirely unfamiliar. Write 56.00 00 (more sets of 0s are optional) under the square root sign. Place a 7 above the 6. Square it, get 49, write that under 56. Subtract, get 7, bring down two zeroes to the right of the 7. Double the 7, get 14, write 14_ to the left of 700. Ask yourself "one-hundred-and-forty-what times that same what equals or is a little less than 700?" It's 4, so you write a decimal point after your square-root 7 and a 4 after it and a 4 in the blank. Multiply 144 times 4 and you get 576. Write this below 700 and subtract. You get 224, then bring down two more zeroes to have 22400. Double your whole square root so far (without decimal point), 74, to get 148 and write 148_ to the left of 22400. Ask yourself the same question as before with "one-thousand-four-hundred-and-eighty-what." Just keep going this same way as long as you like.
