If sqrt3 = 1.732 …. And sqrt(27) = 5.196 ….. " then " (sqrt(27) -sqrt(3))^(2) =

Classify the following numbers as rational or irrational: (3+ sqrt(23)) -sqrt(23)

Classify the following numbers as rational or irrational (3+sqrt(23))-sqrt(23)

7sqrt(3)+2sqrt(27)

The smallest number by which sqrt(27) should be multiplied to get a rational number is (a) sqrt(27) (b) 3sqrt(3) (c) sqrt(3) (d) 3

Do as directed: (i) Add : sqrt(125 + 2 sqrt(27) and - 5 sqrt(5) - sqrt(3) (ii) Add: sqrt(7) - sqrt(11) and sqrt(5) - sqrt(11) + sqrt(13) (iii) Multiply : 2 sqrt(2) by 5 sqrt(2) (iv) Multiply : (-3 + sqrt(5)) by 3 (v) Divide : 7 sqrt(5) by - 14 sqrt(125) Divide : 7 sqrt(5) by -14 sqrt(125) (vi) Divide : 2 sqrt(216) - 3 sqrt(27) by 3

Simplify : sqrt2 - sqrt(18) + sqrt(27) - sqrt(32)

Classify the following numbers as rational or irrational number: (i) sqrt(27) (ii) sqrt(36 (iii) sqrt(5) xx sqrt(125) (iv) 2 sqrt(3) (v) (7 sqrt(7))/(sqrt(343)) (vi) 2 + sqrt(21) (viii) 5 + 2 sqrt(23) - (sqrt(25) + sqrt(92)) (viii) (22)/(7) (ix) pi (x) .^(3)sqrt(37)
