解答

展开

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

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

求解步骤

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

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

使用分配律:

a (b + c) = ab + a c

a = 3, b = lo g_{3} (x), c = lo g_{x} (3) = 10

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

e x p an d x os (t - π)

e x p an d \frac{2}{( s + 1 ) \cdot ( s - 3 )}

e x p an d 3 0^{2} x^{0.5522}

e x p an d \frac{( x ^{2} + 8 ( y + 5 ) ^{2} )}{20}

e x p an d 1 - (\frac{1}{( 1 + x ) ^{20}})
