Answer 2

Answer:

17, 8

Step-by-step explanation:

let one no. be x and the other y

so,

a) x + y = square 625

= x + y = √625

= x + y = 25

We can also write as : y = 25 - x

b) x - y = square 81

= x - y = √81

= x - y = 9

using both the equations,

x - y = 9

= x - (25 - x) = 9

= x -25 + x = 9

= x + x = 9 + 25

= 2x = 34

= x = 34/2

= x = 17

We know: y = 25 - x

= 25 - 17

= 8

So the two no.s are 17 and 8
