What is the square root of this equation v2X-13=11

Question

 What is the above square root of the equation please ?

Answer 1

I assume you mean "solve for x" and the equation is:

 

√(2x-13) = 11

 

Square both sides:

 

(√(2x-13))² = 11²

2x - 13 = 121

2x = 134

x= 67

 

Check:

√(2x-13) = 11

√(2*67-13) = 11

√(134-13) = 11

√121 = 11

11 = 11
