You could also have gotten (ln(ln5)-ln(ln7))/(ln5-ln7)

[@user-ri6rn7ti5h]

√5^√7^x 1^1 (x+1x-1)!

[@mikenoodle100]

Better answer: x=0 Done

[@ramyaadalarasan9588]

nope, if you insert x=0 you will get 5=7. You gotta understand that it is a power tower so that the exponent of the exponent can't multiply with each other.

[@Madosatoshist]

Wrong. That'd give 5==7.
