Question

pleaseee solveeeeeeeeeeee​

Answer 1

Answer:

a) 18 b) 125

Step-by-step explanation:

a) (a-1/a)^2 = (4)^2

a^2 + 1/a^2 -2 = 16

a^2 + 1/a^2 = 16+2

a^2 + 1/a^2 = 18

b) (p + q)^2 = (13)^2

p^2 + q^2 + 2pq = 169

p^2 + q^2 + 2(22) = 169

p^2 + q^2 + 44 = 169

p^2 + q^2 = 169-44

p^2 + q^2 = 125

Answer 2

Here,

a²+1²÷a²

a²+(1÷x)²

(a+1÷a)²-2×a×2÷a

4²-2

16-2
