Answer :

Certainly! Let's take a step-by-step approach to simplify the expression [tex]\( y = \left(\frac{2}{3} x^2 + \frac{1}{2}\right)^4 \)[/tex].

1. Given Expression
[tex]\[ y = \left(\frac{2}{3} x^2 + \frac{1}{2}\right)^4 \][/tex]

2. Simplify Inside the Parenthesis:
Combine the terms inside the parenthesis. We can rewrite the expression as:
[tex]\[ \frac{2}{3} x^2 + \frac{1}{2} \][/tex]
To combine these terms, let's consider the common denominator for 3 and 2, which is 6:

3. Rewrite Each Term with a Common Denominator:
[tex]\[ \frac{2}{3} x^2 = \frac{4}{6} x^2, \quad \text{and} \quad \frac{1}{2} = \frac{3}{6} \][/tex]
Now, our expression inside the parenthesis can be written with the common denominator:
[tex]\[ \frac{4}{6} x^2 + \frac{3}{6} \][/tex]

4. Combine the Fractions:
[tex]\[ \frac{4x^2 + 3}{6} \][/tex]

5. Express the Entire Expression:
Substitute this back into the original equation:
[tex]\[ y = \left( \frac{4x^2 + 3}{6} \right)^4 \][/tex]

6. Observe the Simplification:
We can factorize the fraction out and express the fourth power of a fraction:
[tex]\[ y = \left( \frac{4x^2 + 3}{6} \right)^4 = \left(\frac{1}{6}\right)^4 (4x^2 + 3)^4 \][/tex]

7. Calculate the Constant:
Calculate [tex]\(\left(\frac{1}{6}\right)^4\)[/tex]:
[tex]\[ \left( \frac{1}{6} \right)^4 = \frac{1}{1296} \][/tex]

8. Combine the Constants:
Now, multiply the constant to the polynomial raised to the fourth power:
[tex]\[ y = \frac{1}{1296}(4x^2 + 3)^4 \][/tex]

Given the transformations and the simplifications, we conclude that the simplified form of the given function is:
[tex]\[ y = 0.197530864197531 \left(x^2 + 0.75\right)^4 \][/tex]

So the final expression for [tex]\( y \)[/tex] is:
[tex]\[ y = 0.197530864197531 (x^2 + 0.75)^4 \][/tex]
This result represents the simplified version of the original equation.
