WebAug 31, 2024 · 1. Consider your number and its parts. For whatever number you are observing, the characteristic is the part that comes before the decimal point; the mantissa is the part that comes after the decimal point. [6] As an example, say you need to find the antilog for 2.6452. The characteristic is 2, and the mantissa is 6452. WebExplanation: . Remember that is still a logarithm of a positive number, .. It's not possible to raise to ANY power and obtain a negative number. Because even , for example, is just , which is a ratio of two positive numbers, and therefore positive. More than that, it's also not possible to obtain 0 by raising to any power. Think: "To what power can I exponentiate e …

A logarithm for which the base is not speci ed (y = logx) is always considered to be a base-10 logarithm. 1.2 Easy Logarithms The simplest logarithms to evaluate, which most of you will be able to determine by inspection, are those where y is an integer ...
WebJun 23, 2024 · Explanation: One way we can approach log problems is to remember that. ab = c ⇔ logac = b. In our question, since the value of a in the right hand side log isn't specifically listed, it's assumed to be 10. So what we have is: ab = c ⇔ log10(100) = b. 10b = 100 ⇔ log10(100) = b.
