Simplify The Expression:$\[ 2 \log_3 5 - \log_3 10 + 3 \log_3 4 \\]
Introduction
In mathematics, logarithms are a fundamental concept that plays a crucial role in various mathematical operations. The expression given in this problem involves logarithms with different bases and operations. Our goal is to simplify the given expression using the properties of logarithms.
Understanding Logarithms
Before we dive into simplifying the expression, let's briefly review the concept of logarithms. A logarithm is the inverse operation of exponentiation. In other words, if we have a number x and a base b, the logarithm of x with base b is the exponent to which b must be raised to produce x. This is denoted as logb x.
For example, if we have 2^3 = 8, then log2 8 = 3. Similarly, if we have 10^2 = 100, then log10 100 = 2.
Properties of Logarithms
There are several properties of logarithms that we will use to simplify the given expression. These properties are:
- Product Property: logb (xy) = logb x + logb y
- Quotient Property: logb (x/y) = logb x - logb y
- Power Property: logb (x^y) = y * logb x
Simplifying the Expression
Now that we have reviewed the properties of logarithms, let's simplify the given expression.
2 log3 5 - log3 10 + 3 log3 4
Using the product property, we can rewrite the expression as:
log3 (5^2) - log3 10 + log3 (4^3)
Now, using the power property, we can rewrite the expression as:
2 log3 5 - log3 10 + 3 log3 4
Using the quotient property, we can rewrite the expression as:
log3 (5^2 / 10) + log3 (4^3)
Now, using the product property, we can rewrite the expression as:
log3 (25 / 10) + log3 (64)
Simplifying further, we get:
log3 2.5 + log3 64
Using the product property, we can rewrite the expression as:
log3 (2.5 * 64)
Now, using the product property, we can rewrite the expression as:
log3 160
