\frac{ tan(-x) cosec (-x)}{sec (-x) cot (-x)} ≡ \frac{ [- tan(x)]  [-cosec (-x)]}{[sec (x)] [-cot (x)]}

                                 ≡ \frac{ tan(x) cosec (-x)}{-sec (x) cot (x)} 

                                 ≡ \frac{ (\frac{sin (x)}{cos (x)})   (\frac{1}{sin (x )}) }{(- \frac{1}{cos (x)}) ( \frac{cos (x)}{sin (x)})  }

                                 ≡ \frac{ \frac{1}{cos (x)} }{-  \frac{1}{sin (x)} }

                                 ≡ - \frac{sin (x)}{cos (x)}

                                 ≡ - tan (x)<span>
</span>
⇒ \frac{ tan(-x) cosec (-x)}{sec (-x) cot (-x)} ≡ tan (-x)

I'm assuming that 3(sqrt(x))5 is equal to 15sqrt(x). If that is the case, just perform the multiplication within each term and treat the sqrt(x) as a variable when you add the all together. It is okay because they are like terms.
