Math Problem Statement

log2(8x^2/y) + log2(2xy)

Solution

Let's break down the mathematical expression provided in the image:

log2(8x2y)+log2(2xy)\log_2 \left( \frac{8x^2}{y} \right) + \log_2 (2xy)

We can simplify this expression using logarithmic properties. Specifically, we'll use two key properties:

  1. Product Property of Logarithms: logb(a)+logb(c)=logb(ac)\log_b (a) + \log_b (c) = \log_b (a \cdot c)
  2. Quotient Property of Logarithms: logb(ac)=logb(a)logb(c)\log_b \left( \frac{a}{c} \right) = \log_b (a) - \log_b (c)

Step 1: Apply the product property

We can combine the two logarithmic terms using the product property:

log2(8x2y)+log2(2xy)=log2(8x2y2xy)\log_2 \left( \frac{8x^2}{y} \right) + \log_2 (2xy) = \log_2 \left( \frac{8x^2}{y} \cdot 2xy \right)

Step 2: Simplify the expression inside the logarithm

Now, simplify the expression inside the logarithm:

8x2y2xy=8x22xyy=16x3yy\frac{8x^2}{y} \cdot 2xy = \frac{8x^2 \cdot 2xy}{y} = \frac{16x^3y}{y}

Now the expression simplifies to:

log2(16x3)\log_2 \left( 16x^3 \right)

Step 3: Apply the logarithmic power rule

We can simplify further by using the power rule of logarithms, logb(an)=nlogb(a)\log_b (a^n) = n \cdot \log_b (a):

log2(16x3)=log2(16)+log2(x3)\log_2 (16x^3) = \log_2 (16) + \log_2 (x^3)

log2(16)+log2(x3)=4+3log2(x)\log_2 (16) + \log_2 (x^3) = 4 + 3 \log_2 (x)

Thus, the simplified expression is:

4+3log2(x)4 + 3 \log_2 (x)

Final Answer:

4+3log2(x)4 + 3 \log_2 (x)
