Question

X(√10+√20)(√5-√4)=10

Answer 1

$x( \sqrt{10 } \times \sqrt{5 } + \sqrt{20 } \times \sqrt{5} + \sqrt{10} \times - \sqrt{4} + \sqrt{20} \times - \sqrt{4}) = 10 \\ x( \sqrt{50} + \sqrt{100} - \sqrt{40} - \sqrt{80} ) = 10 \\ x( \sqrt{150} - \sqrt{120}) = 10 \\ x \sqrt{30} = 10 \\ x = 10 \div \sqrt{30}$
