Question

{(13/4)^4 - (13/3)^4} / {(13/4)^2 - (13/3)^2} = (13a/12)^2​ find the value of a

Answer 1

a = +-5

Step-by-step explanation:

after simplifying by using identity

a^2-b^2 = (a-b)(a+b) in LHS we will have,

(13/4)^2 + (13/3)^2 = (13a/12)^2

169/16 + 169/9 = 169a^2/144

25/144 = a^2/144 => a = √25 =+-5
