Math Problem Statement

9^23^51/27 *(1/3)^-4

Solution

Let's break down and simplify the expression step by step:

Given expression:

9235127(13)49^2 \cdot 3^5 \cdot \frac{1}{27} \cdot \left( \frac{1}{3} \right)^{-4}

Step 1: Simplify each term

  1. Simplify 929^2:
    92=819^2 = 81

  2. Simplify 353^5:
    35=2433^5 = 243

  3. Simplify 127\frac{1}{27}:
    127=33\frac{1}{27} = 3^{-3}

  4. Simplify (13)4\left( \frac{1}{3} \right)^{-4}:
    Using the property (1a)b=ab\left( \frac{1}{a} \right)^{-b} = a^b: (13)4=34\left( \frac{1}{3} \right)^{-4} = 3^4

Step 2: Combine powers of 3

Now let's combine the powers of 3.

  • We have: 81243333481 \cdot 243 \cdot 3^{-3} \cdot 3^4

  • Combine the exponents of 3: 353334=353+4=363^5 \cdot 3^{-3} \cdot 3^4 = 3^{5 - 3 + 4} = 3^6

Step 3: Final multiplication

Now, simplify the entire expression:

812433681 \cdot 243 \cdot 3^6

We know that 81=3481 = 3^4 and 243=35243 = 3^5, so the entire expression is:

343536=34+5+6=3153^4 \cdot 3^5 \cdot 3^6 = 3^{4 + 5 + 6} = 3^{15}

Thus, the simplified result of the expression is:

3153^{15}

If you want this in numerical form:

315=14,348,9073^{15} = 14,348,907
