Evaluate:
[tex]\sf \longmapsto \: a {}^{2} + 2ab + b {}^{2} [/tex]
[tex]\sf \longmapsto \: a = 1[/tex]
[tex]\sf \longmapsto \: b = 0[/tex]
The value
Let's start.
[tex]\sf \longmapsto \: a {}^{2} + 2ab + b {}^{2} [/tex]
[tex]\sf \longmapsto1 {}^{2} + 2 ×0×1+0²[/tex]
[tex]\sf \longmapsto(1 \times 1) + 0 +( 0 \times 0) [/tex]
[tex]\sf \longmapsto1 + 0 + 0[/tex]
[tex]\sf \longmapsto1[/tex]
[tex] \boxed{ \boxed{\sf 1 }}[/tex]
