Give exmple of two irrational numbers whose-

i) Sum is rational

ii) Product is rational

iii) Quotient is rational

i) Sum is rational

ii) Product is rational

iii) Quotient is rational

1) (2 + âˆš3) + (2 âˆ’ âˆš3) = 4

2) (2 + âˆš3) Ã— (2 âˆ’ âˆš3) = 22 âˆ’ (âˆš3)2= 4 âˆ’ 3 = 1

3) ï¿½(âˆš5/âˆš5) = 1

2) (2 + âˆš3) Ã— (2 âˆ’ âˆš3) = 22 âˆ’ (âˆš3)2= 4 âˆ’ 3 = 1

3) ï¿½(âˆš5/âˆš5) = 1

If x=3-2âˆš2 , find the value of âˆšx+1/âˆšx.

Given x = 3 â€“ 2âˆš2

â‡’ x = 2 + 1 â€“ 2âˆš2

â‡’ x = (âˆš2)^{2} + 1^{2} â€“ 2 Ã— âˆš2 Ã— 1

â‡’ x = (âˆš2 â€“ 1 )

â‡’ x = 2 + 1 â€“ 2âˆš2

â‡’ x = (âˆš2)

â‡’ x = (âˆš2 â€“ 1 )

FIND FIVE RATIONAL NUMBER BETWEEN 1 AND 2

The rational number between a and b is (a + b)/2

Hence rational number between 1 and 2 is (1+2)/2 = 3/2

Rational number between 1 and 3/2 is [1+(3/2)]/2 = 5/4

Rational number between 1 and ...

Hence rational number between 1 and 2 is (1+2)/2 = 3/2

prove that âˆš7 is irrational ? is âˆš100 same as âˆš(100+ 36) give reasons ?

Sol:

let us assume that âˆš7 be rational.

then it must in the form of p / q [q â‰ 0] [p and q are co-prime]

âˆš7 = p / q

=> âˆš7 x ...
