✔ 最佳答案
-(e+a) log m - h log c - (t+1) log s = - log 35 + log y - (1/3) log 42875 + (2+√-1) log r
where a,c,e,h,i,m,r,s,t,y > 0

ans:
1225=(m^e)rry ‧ (c^h)(r^i)(s^t)(m^a)(s)

-(e+a) log m - h log c - (t+1) log s = - log 35 + log y - (1/3) log 42875 + (2+√-1) log r
log 35 + log [42875^(1/3)]=(e+a) log m + h log c + (t+1) log s + log y + (2+i) log r
log (35‧35) = log m^(e+a) + log c^h + log s^(t+1) + log y + r^(2+i)
log 1225 = log [m^(e+a) ‧ c^h ‧ s^(t+1) ‧ y ‧ r^(2+i)]

2014-02-26 21:17:36 補充:
log 1225 = log [m^(e+a) ‧ c^h ‧ s^(t+1) ‧ y ‧ r^(2+i)]
1225 = m^(e+a) ‧ c^h ‧ s^(t+1) ‧ y ‧ r^(2+i)
1225 = m^e ‧ m^a ‧ c^h ‧ s^t ‧ s ‧ y ‧ r^2 ‧ r^i
1225 = (m^e)(rr)(y) ‧ (c^h)(r^i)(s^t)(m^a)(s)

sorry,
我打多左個i>0
個i唔應該>0

應用題稍後再慢慢想,先試計算題:

(log x)² - log(x²) + 1 = 0
