Math Problem Statement

Simplify the expression \( \log_2 \left( x^5 (x + 2) \right) \).

Solution

The expression in the image is:

log2(x5(x+2))\log_2 \left( x^5 (x + 2) \right)

To simplify or evaluate this logarithmic expression, we can apply the following logarithmic properties:

  1. Product Rule: logb(mn)=logb(m)+logb(n)\log_b(mn) = \log_b(m) + \log_b(n)
  2. Power Rule: logb(mk)=klogb(m)\log_b(m^k) = k \cdot \log_b(m)

Step 1: Apply the product rule

log2(x5(x+2))=log2(x5)+log2(x+2)\log_2 \left( x^5 (x + 2) \right) = \log_2(x^5) + \log_2(x + 2)

Step 2: Apply the power rule to log2(x5)\log_2(x^5)

log2(x5)=5log2(x)\log_2(x^5) = 5 \cdot \log_2(x)

Thus, the expression becomes: 5log2(x)+log2(x+2)5 \cdot \log_2(x) + \log_2(x + 2)

Final Simplified Form:

5log2(x)+log2(x+2)\boxed{5 \cdot \log_2(x) + \log_2(x + 2)}
