Step-by-step explanation:
i)64a²+16a+1. when a=1
=64(1)²+16(1)+1
=64+16+1
=81 and 81 is the perfect square of 9
ii)25a²-30ab+9b² when a=3 b=2
=25(3)²-30(3)(2)+9(2)²
=25(9)-30(6)+9(4)
=225-180+36
=81 and it is perfect square of 9
iii)64-16/p +1/p² whenp=-1
=64-16/-1 +1/(-1)²
=64+16+1
=81 and it is perfect square of9
iv)p²q²+10pqr+25r² whenp=2 q=-1 r=3
= (2)²(-1)²+10(2)(-1)(3)+25(3)²
= 4-60+225
=169 and it is perfect square of 13
