I tried this:

Explanation:

I would try by taking the log in base 7 of both sides:
log_7(2401)^(1/4)=log_7(7)
using a property of logs (exponent of the argument) and the definition of log we get:
1/4log_7(2401)=1
log_7(2401)=1*4
log_7(2401)=4

and so, using the definition of log we have that indeed:
2401=7^4
