Could be +6, -6, +16, or -16.
The square root of a number is the number times itself. e.g. the square root of 4 would be 16, because 4x4 is sixteen. The square root of 5 is 25 because 5x5 is 25.
'Squared' & 'Square Root; are the inverse mathemtical functions. 5 (squared) = 25 square root of '25' is 5 Mathematically this would be written as Square ; 5 x 5 = 5^(2) = 25 Square Root ; sqrt(25) = 25^(1/2) = 25^(0.5) = 5 NB THis can be exteneded to 'cubes' and 'cube roots' e.g. 3 x 3 x 3 = 3^(3) = 27 curt(27) = 27^(1/3) = 27^(0.3333.....) - 3 And fourth power and fourth root. e.g. Fourth power ; 2 x 2 x 2 x 2 = 2^(4) = 16 Fourth root = (4th)rt(16) = 16^(1/4) = 16^(0.25) = 2 It can be exteneded to the 'nth power' and the 'nth root'. Where 'n' is any number.

The square root of 25 plus the square root of 36 = 11
what number times itself = 16, that is what you are trying to find. 4 x 4= 16 so the square root of 16 =4 square root of 25 is 5 because 5 x 5 is well 25.
Could be +6, -6, +16, or -16.
30. Square root is a number, times itself. 30x30 =900. Other examples of square root are 4x4=16, so 4 is the square root of 16. 5x5=25, so 5 is the square root of 25. 10 is the square root of 100, because 10x10=100.
The numbers are: (25-square root of 505)/2 and (25+square root of 505)/2
Square root of 25 = +or- 5 Square root of -36 = +or- 6i where i is the imaginary number such that i^2=-1 Square root of 121 = +or-11 So the 8 possible answers are: -16-6i, -16+6i, -6-6i, -6+6i, 6-6i, 6+6i, 16-6i and 16+6i
The square root of a number is the number times itself. e.g. the square root of 4 would be 16, because 4x4 is sixteen. The square root of 5 is 25 because 5x5 is 25.

Where 'n' is any number.
The wording is a little ambiguous, so this could be interpreted two ways. Remember that √(a*b) = (√a)*( √b), so:If it is √(16*25) = (√16)*(√25) = 4*5 = 20. Note that -20 is also an answer.If it is (√16)*25 = (4)*25 = 100 [-100 is also an answer.]
9 + 16 = 25
