Question

2 + 3 root 5 upon 7 - root 5=a + b root 5

Answer 1

Step-by-step explanation:

take root 5 as common

then

root 5 ( 2 + 3/7 - 1 ) = a + b (root 5 )

= root 5 ( 17/7 -1 ) = a + b ( root 5 )

= root 5 ( 10/ 7) = a + b ( root 5 )

= root 5×10 / 7 - b (root 5) = a

= root 5 ( 10 / 7 - b ) = a

= root 5 ( 10 - 7b / 7 ) = a

hope this is correct............
