simplify (sqrt(5)+sqrt(3))^2+(sqrt(5)-sqrt(3))^2

simplify

(5 + 3)^{2} + (5 - 3)^{2}

16

Solution steps

(5 + 3)^{2} + (5 - 3)^{2}

(5 + 3)^{2} = 8 + 215

(5 - 3)^{2} = 8 - 215

= 8 + 215 + 8 - 215

8 + 8 = 16

= 16

cot (θ) + tan (θ)

20 x^{10} y^{8}

\frac{2}{3} \cdot \frac{3}{8}

\frac{64 x y ^{5}}{8 x}

\frac{a ^{2} - b ^{2}}{b ^{2} + ab} + \frac{a ^{2} - b ^{2}}{a ^{2} - ab}
