Web21 de fev. de 2024 · Description. Because log () is a static method of Math, you always use it as Math.log (), rather than as a method of a Math object you created ( Math is not a constructor). If you need the natural log of 2 or 10, use the constants Math.LN2 or Math.LN10. If you need a logarithm to base 2 or 10, use Math.log2 () or Math.log10 (). Web14 de fev. de 2016 · 59. To evaluate log8128, let log8128 = x Then by definition of the logarithm, 8x = 128 Since 8 = 23 and 128 = 27, we obtain (23)x = 27 23x = 27 If two exponentials with the same base are equal, then their exponents must be equal. Hence, 3x = 7 x = 7 3. Check: If x = 7 3, then 8x = 87 3 = (81 3)7 = 27 = 128. Share.
