Question

Lgx=2-lg5

Answer 1

Ответ lgx=lg10^2-lg5 2=lg10^2 это ф -ла log 10^2 по основанию 10=2 у нас одинаковые основания мы их можем опустить получим x=10^2\5 x=100\5 x=20

Answer 2

To simplify the expression Lgx = 2 - lg5, let's break it down step by step.

First, let's simplify the logarithm term lg5. Assuming that "lg" represents the logarithm with base 10, we can calculate lg5 using a calculator or mathematical software:

lg5 ≈ 0.69897

Now we substitute this value back into the expression:

Lgx = 2 - 0.69897

Next, we subtract 0.69897 from 2:

Lgx ≈ 1.30103

Therefore, Lgx ≈ 1.30103.
