Question 987864
{{{something*something=50}}}, both "something" must be the same.


{{{sqrt(50)sqrt(50)=50}}}


You should know from basic multiplication facts that  50 is near 49, and {{{sqrt(49)=7}}}.  You should expect that sqrt(50) is larger than 7 but much less than 8.


{{{sqrt(50)}}}
{{{sqrt(5*2*5)}}}
{{{sqrt(5*5*2)}}}
{{{sqrt(5)sqrt(5)sqrt(2)}}}
{{{5sqrt(2)}}}


If you'all know how to find an approximation for square root of two, then you can just perform the multiplication.
1.4142 is APPROXIMATELY square root of 2.
