1)  2\sqrt{2} + 3 \sqrt{2} +  \frac{1}{4} * 4 \sqrt{2} + 10 \sqrt{2} = 16 \sqrt{2}

2) a^{5}b^{3}c^{7}  \frac{9c ^{2} }{10 ^{3} }  \frac{6 ^{2} }{8a ^{7} } =  \frac{81}{2000}} \frac{1}{ a^{2} }  b^{3}  c^{9}

3) \frac{30a ^{5} b}{6a ^{3}b ^{8} } ( \frac{6b ^{3} a ^{2} }{3a ^{3} }) ^{2} =  5 a^{2} b^{-7}  4 b^{6} a^{-2} = \frac{20}{b}

\frac{30a ^{5} b}{6a ^{3}b ^{8} } ×( \frac{6b ^{3} a ^{2} }{3a ^{3} }) ^{2}
gmn ngerti??
ya udah gak usah maksih
hmm maksudny?
makasih ya
