Tính :
\(A=2\sqrt{\left(-3\right)^6}+2\sqrt{\left(-2\right)^4}-4\sqrt{\left(-2\right)^6}\)
\(B=\sqrt{\left(\sqrt{2}-2\right)^2}+\sqrt{\left(\sqrt{2}-3\right)^2}\)
\(C=\sqrt{\left(3-\sqrt{3}\right)^2}-\sqrt{\left(1+\sqrt{3}\right)^2}\)
\(D=\sqrt{\left(5+\sqrt{6}\right)^2}\)
\(E=\sqrt{17^2}-8^2-\sqrt{3^2+4^2}\)
ai giúp mình với ạ ;-;
\(A=2\sqrt{\left(-3^3\right)^2}+2\sqrt{\left(-2^2\right)^2}-4\sqrt{\left(-2^3\right)^2}\)
\(A=2\left|-3^3\right|+2\left|-2^2\right|-4\left|-2^3\right|\)
\(2.27+2.4-4.8\)
\(A=30\)
\(B=\sqrt{\left(\sqrt{2}-2\right)^2}+\sqrt{\left(\sqrt{2}-3\right)^2}\)
\(B=\left|\sqrt{2}-2\right|+\left|\sqrt{2}-3\right|\)
\(B=2-\sqrt{2}+3-\sqrt{2}\)
\(B=5-2\sqrt{2}\)
\(C=\sqrt{\left(3-\sqrt{3}\right)^2}-\sqrt{\left(1+\sqrt{3}\right)^2}\)
\(C=\left|3-\sqrt{3}\right|-\left|1+\sqrt{3}\right|\)
\(C=3-\sqrt{3}-1-\sqrt{3}\)
\(C=2-2\sqrt{3}\)
\(D=\sqrt{\left(5+\sqrt{6}\right)^2}\)
\(D=5+\sqrt{6}\)
\(E=\sqrt{17^2}-8^2-\sqrt{3^2+4^2}\)
\(E=17-64-\sqrt{25}=17-64-5=-52\)
