What is (x+y)^4???????????/

(x+y)^4 = (x+y)² × (x+y)² = (x²+2xy+y²)(x²+2xy+y²) = x⁴+4x³y+6x²y²+4xy³+y⁴. If you know binomial theorem, its faster.-((x + y)^2)*(x + y)^2 = (x^2 + 2*x*y + y^2)*(x^2 + 2*x*y + y^2) = x^4 + 4*x^3*y +

Verify 100/ 1 + 2 ^ (-log base2 (x/100-x) is X

100 / (1 + 2^(-log₂(x/(100-x)))) = 100 / (1 + 1/(2^(log₂(x/(100-x))))) = 100 / (1 + 1/(x/(100-x))) = 100 / (1 + (100-x)/x) = 100x / (x(1 + (100-x)/x)) = 100x / (x + 100 - x) = 100x / 100 = x.
