Answer 2

Solving the Expression lg(20) + lg(2) - lg(0.04)

To solve the expression lg(20) + lg(2) - lg(0.04), let's break it down step by step.

1. lg(20): - The logarithm of 20 to the base 10 is approximately 1.3010. - Source: [[1]]

2. lg(2): - The logarithm of 2 to the base 10 is approximately 0.3010. - Source: [[2]]

3. lg(0.04): - The logarithm of 0.04 to the base 10 is approximately -1.3979. - Source: [[3]]

Now, let's substitute these values back into the original expression:

lg(20) + lg(2) - lg(0.04) = 1.3010 + 0.3010 - (-1.3979)

Solving this, we get:

lg(20) + lg(2) - lg(0.04) ≈ 1.3010 + 0.3010 + 1.3979 ≈ 2.9999

So, the value of lg(20) + lg(2) - lg(0.04) is approximately 2.9999.
