$1)2 ^{4/3+2/3} *3 ^{2/3+7/3} =2^2*3^3=4*27=108$
$2)(3/2)^2- \sqrt[3]{1/27} +3*1=9/4-1/3+3=(27-4+36)/12=59/4$ =14,75
$3) \sqrt[3]{128/2} + \sqrt[3]{1/4*1/2} = \sqrt[3]{64} + \sqrt[3]{1/8} =4+1/2=4,5$
2
$\sqrt[3]{(ab^2*a^5b)/(c*c^2)} = \sqrt[3]{a^6b^3/c^3} =a^2b/c$
3
$1) \sqrt{a} ( \sqrt[4]{a} -3)( \sqrt[4]{a} +3)/7( \sqrt[4]{a} +3)=$ $\sqrt{a} ( \sqrt[4]{x} -3)/7$
$2)( \sqrt{x} +1)/( \sqrt{x} +1)( \sqrt{x} -1)=1/( \sqrt{x} -1)$
