Find: (sqrt7 +sqrt3)(3-sqrt3)

The value of |{:(sqrt(13 )+ sqrt(3), 2sqrt(5),sqrt(5)),(sqrt(15) + sqrt(26),5,sqrt(10)),(3 + sqrt(65), sqrt(15),5):}|

Write the conjugate of sqrt(-25) (7+ sqrt(-576))

Find : (sqrt5+sqrt2)(sqrt3+sqrt2)

Evaluate : sqrt(248 + sqrt(52 + sqrt(144)))

Find (sqrt 3 - sqrt 5)(sqrt 5+ sqrt3)

Evaluate the sqrt(20-sqrt(16))

Find sqrt(2+3sqrt(-5)) + sqrt(2-3sqrt(-5))

Evaluate : (15)/(sqrt(10)+sqrt(20)+sqrt(40)-sqrt(5)-sqrt(80)), is being given that sqrt(5)=2. 236 and sqrt(10)=3. 1362

The simplest rationalising factor of 2sqrt(5)-sqrt(3) is (a) 2sqrt(5)+\ 3 (b) 2sqrt(5)+sqrt(3) (c) sqrt(5)+sqrt(3)\ \ (d) sqrt(5)-sqrt(3)
