These are simple square route problems, It is better to learn multiplication tables well and you can determine these questions in your head, but with a calculaor you can take the square route of 49 and you get the even number 7. this means that 7^2 (squared)=49 if you do not get an even number you have to look for perfect squares in the number. to leave as a square route function place the 2 in front of the square route sign over 7.
perfect squares are
1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121 ect.
