solvefor d,5ln(d^2+yx)=7

解答

求解

d, 5 ln (d^{2} + y x) = 7

解答

d = e^{\frac{7}{5}} - y x, d = - e^{\frac{7}{5}} - y x

求解步骤

5 ln (d^{2} + y x) = 7

两边除以

5

ln (d^{2} + y x) = \frac{7}{5}

使用对数运算法则

d^{2} + y x = e^{\frac{7}{5}}

解

d^{2} + y x = e^{\frac{7}{5}} : d = e^{\frac{7}{5}} - y x, d = - e^{\frac{7}{5}} - y x

d = e^{\frac{7}{5}} - y x, d = - e^{\frac{7}{5}} - y x

2log_{4}(x)-log_{4}(x+3)=1

2 lo g_{4} (x) - lo g_{4} (x + 3) = 1

ln(x^2)+ln(x)=2

ln (x^{2}) + ln (x) = 2

- ln (1 - x) = 0

log_{2}(c)=4+log_{2}(c-3)

lo g_{2} (c) = 4 + lo g_{2} (c - 3)

log_{2}(x+22)=3

lo g_{2} (x + 22) = 3
