Question

A by b + b by a. b is 6 and a is 4​

Answer 1

Explanation:

`(4)/(6)`+
`(6)/(4)`

LCM- 12

`(4)/(6) * (2)/(2)`=
`(8)/(12)`

&

`(6)/(4) * (3)/(3)`=
`(18)/(12)`

`(18 + 8)/(12)`=
`(26)/(12)`

now, since it's an improper fraction, we would convert it to mixed.

`\sqrt[12]{26}`=
`2 (2)/(12)`

here's your answer.

Answer 2

=a ×by ×b +b×by ×a

=(4×6×y×6) +(6×6×y×4)

=144y +144y

=288y
