Hey can anyone tell me how to solve these types of questions,
\( \frac {(8^4 + 64) ( 16^4 + 64)(24^4+64)(32^4+64)(40^4+64)(48^4 + 64)(56^4+64)(64^4+64) }
{ (4^4+64)(12^4+64)(20^4+64)(28^4+64)(36^4+64)(44^4+64)(52^4+64)(60^4+64) }. \)
thank you

Actually I wanted to give it but i wasn't able to download the paper on mobile :-( I'll try it later.....by the way why are you asking me about it ?????

`2^{34}`

`a_{i-1}`

`\frac{2}{3}`

`\sqrt{2}`

`\sum_{i=1}^3`

`\sin \theta`
