Solve y^2= 49 , where y is a real number 
Simplify your answer as much as possible 
                                             
                                          
                                          
                                        
											 
											[tex] {y}^{2} = 49[/tex]
Move the square to the right-hand side and convert it to underoot
[tex]y = \sqrt{49} [/tex]
Calculate the root of 49
[tex]y = 7 \:or -7[/tex]
Answer:
y = +7 or -7
Step-by-step explanation:
y^2 = 49
square rooting both sides
y = √49
y = +7 or -7
