solvefor x,log_{w}(x+4)=t

解答

求解

x, lo g_{w} (x + 4) = t

x = w^{t} - 4

求解步骤

lo g_{w} (x + 4) = t

使用对数运算法则

x + 4 = w^{t}

解

x + 4 = w^{t} : x = w^{t} - 4

x = w^{t} - 4

6 ln (x) = 15.6

6.5 = 4.5 + lo g_{3} (t + 1)

- 140000 = - (8.314) (837.15) ln (x)

4 lo g_{8} (2) = lo g_{8} (x)

7 = 8.214 + lo g_{10} (x)
