Answer:
The above statement is True
Step-by-step explanation:
1st method
w^2+18w+81=(w+9)^2
w^2+9w+9w+81=(w+9)^2
w(w+9)+9(w+9)=(w+9)^2
(w+9)(w+9)=(w+9)^2
(w+9)^2=(w+9)^2
L.H.S=R.HS
Hence Proved
2nd method
w^2+18w+81=(w+9)^2
w^2+18w+81=(w+9)(w+9)
w^2+18w+81=w^2+9w+9w+9×9
w^2+18w+81=w^2+18w+81
L.H.S=R.HS
Hence Proved
