Question

resolução do binômio (√x + √y)⁴​

Answer 1

${(a+b)}^{4}={a}^{4}+6{a}^{2}{b}^{2}+4a{b}^{3}+{b}^{4}$

${(\sqrt{x}+\sqrt{y})}^{4}\\={(\sqrt{x})}^{4}+6{(\sqrt{x})}^{2}{(\sqrt{y})}^{2}+4\sqrt{x}{(\sqrt{y})}^{3}+{(\sqrt{y})}^{4}$

${(\sqrt{x}+\sqrt{y})}^{4}\\={x}^{2}+6xy+4\sqrt{x}{(\sqrt{y})}^{3}+{y}^{2}$
