(3x-4)^5 x(sqaure root)9x^2+4

To simplify the expression, we will follow the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Let's break down the given expression step by step:

1. Starting inside the parentheses:
(3x - 4)^5 = (3x)^5 - 4^5
= 243x^5 - 1024

2. Next, we simplify the square root term:
√(9x^2 + 4) is not a perfect square, so we cannot simplify it further.

3. Now, we multiply the two simplified terms together:
(243x^5 - 1024) * √(9x^2 + 4)

This is the final simplified expression.
