given:
[tex] {(60)}^{2} [/tex]
to find:
evaluate using suitable identity.
solution:
suitable identity=
[tex] {(a + b)}^{2} = {a}^{2} + 2ab + {b}^{2} [/tex]
[tex]a = 58[/tex]
[tex]b = 2[/tex]
[tex] = {(58 + 2)}^{2} = {58}^{2} + 2(58)(2) + {2}^{2} [/tex]
[tex] {60}^{2} = 3364 + 232 + 4[/tex]
[tex] {60}^{2} = 3600[/tex]
