Dear student
As we know
Tan 5x = tan (3x + 2x)
Tan 5x = tan 3 x + tan2x / 1 - tan 3x tan2x
Tan5 x - tan5x tan3x tan2x = tan 3x + tan2x
Tan5x - tan3x - tan2x = tan 2x tan 5x tan3x
Hence
Now use this
Hence question becomes as
tan 2x tan3x tan5x /30 x³
= Tan 2x /2x * tan 3x /3x * tan5x/5x
= 1
Hope it helps
