Show that `(sqrt(7) + isqrt(3)) / (sqrt(7) - isqrt(3)) + (sqrt(7) - isqrt(3)) / (sqrt(7) + isqrt(3))`, is real.

Multiply : sqrt(3)(sqrt(7)-sqrt(3))

Multiply: (sqrt(5)-sqrt(7))sqrt(2)

Find the value of: ((1 + isqrt(3)) / (1 - isqrt(3)))^6 + ((1 - isqrt(3)) / (1 + isqrt(3)))^6 using De Moivre's Theorem

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

Simplify: 7sqrt(48)-sqrt(27)-sqrt(3)

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