```							To solve this equation you have to firstly convert tan in sin and cosin and then by taking LCM and using formula sin(a)cos(b)+cos(a)sin(b)  we can get the answer  i.e.Tan5a = sin 5a / cos 5aTan3a= sin 3a / cos 3aPutting values in equation and taking LCM we will get[(sin 5a)(cos 3a) + (cos 5a)(sin 3a)]  / [(sin 5a)(cos 3a) - (cos 5a)(sin 3a)]Now using formula (sina)(cosb) + (cosa)(sinb) = sin(a+b)(sina)(cosb) - (cosa)(sinb) = sin(a-b)We will get sin8a/sin2a
