= ((√3/2)/(1/2))/(√2/2) = (√3)/(√2/2) = (2√3)/(√2)
= ((2√3)(√2))/((√2)(√2)) = (2√6)/2 = √6
If any step doesn't makes sense, hmu!

Step-by-step explanation:
We are given that![\frac{tan60^{\circ}}{cos45^{\circ}}](/tpl/images/0160/2197/19f48.png)
We have to evaluate tan 60 degrees over cos 45 degrees
We know that![tan 60=\sqrt3](/tpl/images/0160/2197/4ef53.png)
Substitute the values then we get
When a denominator in fraction then the number in the denominator of denominator fraction will convert into multiply
Suppose , we have
Using this rule
Hence,![\frac{tan60^{\circ}}{cos45^{\circ}} =\sqrt6](/tpl/images/0160/2197/b71b3.png)
