[" Q9.Solve "],[(5+sqrt(7))times(5-sqrt(7))]

Solve : ((4+ sqrt(7)))/3 times ( (4- sqrt7))/3

Solve : 7/ sqrt(5) times 4/ sqrt(5)

5/(sqrt(5)-sqrt(7))

Multiply 3sqrt(7) by 5sqrt(7)

Simplify : sqrt(7)-3/5sqrt(7)+2sqrt(7)

Evaluate : sqrt(5)/ (sqrt(7) - sqrt(5)

Evaluate : (1+sqrt7)^5+(1-sqrt7)^5

(5sqrt(7)+2sqrt(7))(6sqrt(7)+3sqrt(7))=?

show that (sqrt(7)-sqrt(5))/(sqrt(7)+sqrt(5))times(sqrt(7)-sqrt(5))/(sqrt(7)-sqrt(5)) =frac{(sqrt(7)-sqrt(5))^(2)}{2}

Solve: sqrt(4x-9)+sqrt(4x+9)= 5+sqrt7 .
