Question

Evaluate the following
i) (p2+q2)(p2-q2)​

Answer 1

Step-by-step explanation:

(p2) ² - (q2) ² [(a+b)(a-b) = a²-b²]

p²4 - q²4

4(p²-q²) ANSWER

Answer 2

Answer:

$( {p}^{2} + {q}^{2} )( {p}^{2} - {q}^{2} ) \\ \\ using \: formula \\ \\ {a}^{2} - {b}^{2} \\ \\ = ( a+ b)( a- b) \\ \\ here \: a \: = {p}^{2} \: and \: b = {q}^{2} \\ \\ so \: ( {p}^{2} )^{2} - ( {q}^{2} ) ^{2}\\ \\=p^4 - q^4$

hope it helps uH :)
