Answer 2

Answer: 16 and 12

Step-by-step explanation:

√256 = 16

at least that is the positive square root

16^{2} =(-16)^{2} = 256

-16 is also a square root of 256

√{x} = |x|

this is the formula for square root

the same formula would be used for the square root of 12

√144=12

12{^2}= (-12){^2}=144

By definition, the principal square root of a number is the positive square root. The term "the square root" is commonly used to refer to the principal (positive) root though there are usually two roots.
