Answer 1

YOUR FIRST QUESTION :–

given no. = 0.2575757......

let x be the given no.

x= 0.25757.... ..(equation 1)

therefore, 1000x = 0.25757.....× 1000

= 257.5757..... ..(equation 2)

subtracting equation 1 from equation 2, we get :–

1000x - x = 257.5757...- 0.25757...

999x = 257

257

x = ––––

999

YOUR 2nd QUESTION :—

(4+4√7) (5+3√7)

= 4(5+3√7) + 4√7(5+3√7)

= 20 + 12√7 + 20√7 + {(4×3) (√7×√7)}

= 20 + (12√7 + 20√7) + (12×7)

= 20 + 32√7 + 84

= 20 + 84 + 32√7

= 104 + 32√7

YOUR 3rd QUESTION :–
