Math Problem Statement

how to solve numer 1?

Solution

To solve problem 1, we need to simplify the expression given:

(22n)2(4n)n1(2n)2n+1\frac{(2^{2n})^2 \cdot (4^n)^{n-1}}{(2^n)^{2n+1}}

Let's break it down step by step.

Step 1: Simplify the Numerator

The numerator is (22n)2(4n)n1(2^{2n})^2 \cdot (4^n)^{n-1}.

  1. (22n)2(2^{2n})^2: (22n)2=22n2=24n(2^{2n})^2 = 2^{2n \cdot 2} = 2^{4n}

  2. (4n)n1(4^n)^{n-1}: 4n=(22)n=22n4^n = (2^2)^n = 2^{2n} (22n)n1=22n(n1)=22n22n(2^{2n})^{n-1} = 2^{2n \cdot (n-1)} = 2^{2n^2 - 2n}

So the numerator becomes: 24n22n22n=24n+2n22n=22n2+2n2^{4n} \cdot 2^{2n^2 - 2n} = 2^{4n + 2n^2 - 2n} = 2^{2n^2 + 2n}

Step 2: Simplify the Denominator

The denominator is (2n)2n+1(2^n)^{2n+1}.

  1. (2n)2n+1(2^n)^{2n+1}: (2n)2n+1=2n(2n+1)=22n2+n(2^n)^{2n+1} = 2^{n \cdot (2n+1)} = 2^{2n^2 + n}

Step 3: Combine Numerator and Denominator

Now we have: 22n2+2n22n2+n\frac{2^{2n^2 + 2n}}{2^{2n^2 + n}}

Using the exponent subtraction rule aman=amn\frac{a^m}{a^n} = a^{m-n}, we get: 2(2n2+2n)(2n2+n)=22n2+2n2n2n=2n2^{(2n^2 + 2n) - (2n^2 + n)} = 2^{2n^2 + 2n - 2n^2 - n} = 2^n

So, the simplified form of the given expression is: 2n2^n
