10

اقسم الطرفين على

lo g_{10} (x^{2}) = - 2

فعّل قانون اللوغارتمات

x^{2} = \frac{1}{100}

x^{2} = \frac{1}{100}

حلّ:

x = \frac{1}{10}, x = - \frac{1}{10}

x = \frac{1}{10}, x = - \frac{1}{10}

افحص الإجبات:

x = \frac{1}{10}

صحيح

, x = - \frac{1}{10}

صحيح

The solutions are

x = \frac{1}{10}, x = - \frac{1}{10}

أمثلة شائعة

25^{log_{5}(3x^2)}=9x^2

2 5^{l o g_{5} (3 x^{2})} = 9 x^{2}

log_{10}(x)=-13.9

lo g_{10} (x) = - 13.9

log_{2}(x+19)+log_{2}(x+4)=4

lo g_{2} (x + 19) + lo g_{2} (x + 4) = 4

x^{1+ln(x)}=e^4*x

x^{1 + l n (x)} = e^{4} \cdot x

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