-7*3^(0.25x) = -10      divide both sides by -7

 

3^(0.25x)  =  10/7      take the log of both sides

 

log 3^(0.25x)  = log(10/7)      and we can write

 

(0.25x) * log 3  =  log(10/7)

 

x * (0.25)log 3  = log(10/7)        diide both sides by (0.25)log3

 

x  = log(10/7) / [ (0.25 log 3 ] ≈  1.299
