Question

7 root 3 -5root 2/ root 48b+root 18​

Answer 1

Answer:

= (7√3 - 5√2) / (√48 + √18)

= (7√3 - 5√2) / (√16.3 + √9.2)

= (7√3 - 5√2) / (4√3 + 3√2)

= (7√3 - 5√2)/ (4√3 + 3√2). (4√3 - 3√2)/(4√3 - 3√2)

= 7√3(4√3 - 3√2) - 5√2(4√3 - 3√2) / 4√3(4√3 - 3√2) + 3√2(4√3 - 3√2)

= (28√9 - 21√6 - 20√6 + 15√4) / (16√9 - 9√4)

= (28(3) - 41√6 + 15(2)) / (16(3) - 9(2))

= (84 - 41√6 + 30) / (48 - 18)

= (114 - 41√6) / 30
