Given that x2−y2=(x−y)(x+y) x^2 - y^2 = (x-y) ( x+y)x2−y2=(x−y)(x+y), what is the value of 312−192 31 ^2 - 19 ^2 312−192?
Given that a4−b4=(a2−b2)(a2+b2)=(a−b)(a+b)(a2+b2) a^4 - b^4 = (a^2 - b^2)(a^2 + b^2) = (a-b)(a+b)(a^2 + b^2 ) a4−b4=(a2−b2)(a2+b2)=(a−b)(a+b)(a2+b2), what is the value of 54−44 5 ^4 - 4 ^4 54−44?
If x+y=6x+y=6x+y=6, x−y=2x-y=2x−y=2 and x2+y2=20x^2+y^2=20x2+y2=20, what is the value of x4−y4?x^4-y^4?x4−y4?
