Question

Solve for m. M 5 = 3 2 o 2,5-6 6 - 2.5 06+2.5

Answer 1

`(√(77))/(22)`

1) Consider this ratio. Since there is one radical in the denominator, we can rationalize it to simplify it:

`(√(7))/(2√(11))=`

2) Let's multiply both numerator and denominator by its conjugate:

`(√(7))/(2√(11))=(√(7)\cdot√(11))/(2√(11)\cdot√(11))=(√(77))/(2√(11^2))=(√(77))/(22)`

Note that we rationalize it to simplify calculations. And we do that by getting rid of any radical on the bottom number as much as we can.
