Chapter 5: Q 113. (page 309)

Write an example that illustrates whylog2x+y鈮�log2x+log2y.

Short Answer

Expert verified

The solution is explained in steps.

Step by step solution

01

Step 1. Find the value on the left side.

Substitute 9, and 2, for x, and yin log2x+y.

log2x+y=log29+2=log211鈮�3.45943

02

Step 2. Find the value on the right side.

Substitute 9, and 2, for x, and yin log2x+log2y.

log2x+log2=log29+log22=3.16992+1=4.16992

03

Step 3. Conclusion.

After substituting the values, the value of both functions is different. Thus, both functions are not equal.
