Math Problem Statement

The expression (2^4 * 2^3 * 2^-3) / √(4^2 * 2^4 * 2^-3) equals 2^n, where n is:

Solution

Let's analyze the given mathematical expression:

242323422423=2n\frac{2^4 \cdot 2^3 \cdot 2^{-3}}{\sqrt{4^2 \cdot 2^4 \cdot 2^{-3}}} = 2^n

We need to simplify this expression step by step to find the value of nn.

Step 1: Simplifying the numerator

The numerator is:

2423232^4 \cdot 2^3 \cdot 2^{-3}

Using the property of exponents aman=am+na^m \cdot a^n = a^{m+n}, we combine the powers of 2:

242323=24+33=242^4 \cdot 2^3 \cdot 2^{-3} = 2^{4 + 3 - 3} = 2^4

Step 2: Simplifying the denominator

The denominator is the square root expression:

422423\sqrt{4^2 \cdot 2^4 \cdot 2^{-3}}

First, express 424^2 as (22)2=24(2^2)^2 = 2^4:

242423=24+43=25\sqrt{2^4 \cdot 2^4 \cdot 2^{-3}} = \sqrt{2^{4+4-3}} = \sqrt{2^5}

Now, simplify the square root of 252^5:

25=25/2\sqrt{2^5} = 2^{5/2}

Step 3: Putting it all together

Now the expression becomes:

2425/2\frac{2^4}{2^{5/2}}

Using the property aman=amn\frac{a^m}{a^n} = a^{m-n}:

245/2=28252=2322^{4 - 5/2} = 2^{\frac{8}{2} - \frac{5}{2}} = 2^{\frac{3}{2}}

Thus, we have:

2n=2322^{n} = 2^{\frac{3}{2}}

Step 4: Conclusion

Therefore, n=32n = \frac{3}{2}.
