xlog_{10}(3)+5=xlog_{10}(9)

解答

x \cdot lo g_{10} (3) + 5 = x \cdot lo g_{10} (9)

解答

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

+1

十进制

x = 10.47951 \dots

求解步骤

x lo g_{10} (3) + 5 = x lo g_{10} (9)

将

5

到右边

x lo g_{10} (3) = 2 lo g_{10} (3) x - 5

将

2 lo g_{10} (3) x

para o lado esquerdo

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

两边除以

- lo g_{10} (3)

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

solvefor x,6x+5y-82=0

so l v e f or x, 6 x + 5 y - 82 = 0

3 x + 40 = 12 x - 14

solvefor x,y^2(x-2)+2=0

so l v e f or x, y^{2} (x - 2) + 2 = 0

2 y - 3 = 2 y - 2

f(u^1-u^2)=f(u^1)-f(u^2)

f (u^{1} - u^{2}) = f (u^{1}) - f (u^{2})
