Suppose  N is a natural number such that N=M^2 . The number M is called square root of M

Suppose  N is a natural number such that N=<math> M^2 </math> . The number M is called square root of M

we have m^2=mxm or (-m)x(-m)=(-m)^2 thus m2 has 2 squer roots, m;m and m example 9=3^2 or (-3)^2.thus both 3 and -3 or squer roots of 9

we have <math>m^2</math>=mxm or (-m)x(-m)=<math>(-m)^2</math> thus <math>m^2</math> has 2 squer roots, m;m and m example 9=<math>3^2</math> or <math>(-3)^2</math>.thus both 3 and -3 or <math>\sqrt9</math>
