About 3??
Hope it is somehow helpful
x^2=10
Something times itself is ten, so i think it is a decimal 3 like 3.(???) i am not sure what exactly the number is but it is about 3
you should do the quare root of 10 and see what you get ;-; sorry if my answer sucks
The value of x is 5 because 10 divided by 2 = 5 and 2 x 5 = 10, hope I helped :)
