Question

2under root 3 X 3 under root 3 - 9X2 ​

Answer 1

Answer:

Step-by-step explanation:

2√3 x 3√3 - 9x2

2x3x√3x√3 = 6 x 3 = 18

18 - 9x2 = 18 - 18 = 0

Answer 2

$(\sqrt[3]{2} )( \sqrt[3]{3} ) = \sqrt[3 \: ]{6} \\ \\ \sqrt[3]{6} - 18 = \sqrt[3]{6} - \sqrt[3]{5832} = \\ \\ \sqrt[3]{6} - \sqrt[3]{6 \times 972} = \\ \\ \sqrt[3]{6} (1 - \sqrt[3]{972} ) \\ \\ \\ post$
