Answer: 10
Step-by-step explanation:
The sign √ means square root. Squaring is like multiplying a number by its own self again ( for example, x times x is equal to x squared). A square root is like dividing the square by its own self ( for example, √x^2 is equal to x ).
The square root of 100 is 10, since 10 squared is equal to 100.
