log_{10}(5)(x)=3

解答

lo g_{10} (5) (x) = 3

x = \frac{3}{lo g _{10} ( 5 )}

十进制

x = 4.29202 \dots

求解步骤

lo g_{10} (5) (x) = 3

两边除以

lo g_{10} (5)

x = \frac{3}{lo g _{10} ( 5 )}

(\frac{2}{5}) 125 = (180 - 125) - 5

v = - 2 i + n - 3 a_{0}

so l v e f or b, a = 2 b + c

(8 x - 2) (3 x + 4) = (4 x + 3) (6 x - 2)

12 x + 2 = 10 x + 6
