If `(2x^2-y^2)^4=256 and (x^2+y^2)^5=243`, then find `x^4-y^4` The following steps are involved in solving the above problem. Arragne then in sequential order. (A) `(x^2-y^2)^4=256=4^4 and (x^2+y^2)^5=3^5` (B) `x^4-y^4=12` (C) `(x^2-y^2)(x^2+y^2)=4xx3`(D) `x^2-y^2=4 and x^2+y^2=3`A. ADCDB. ABCDC. ADBCD. ACDB
