Answer :
n² - 49 = 0
+ 49 + 49
n² = 49
n = +7
The solution to the problem is {7, -7}.
+ 49 + 49
n² = 49
n = +7
The solution to the problem is {7, -7}.
So [tex] n^{2} - 49 = 0 [/tex]
Add 49 from 0 and you get
[tex]n ^{2} = 49[/tex]
Only [tex] 7^{2} [/tex]= 49 so n = 7
Add 49 from 0 and you get
[tex]n ^{2} = 49[/tex]
Only [tex] 7^{2} [/tex]= 49 so n = 7
