Simplify the following expression and find the value of [tex]\( \left.x \cdot \frac{1}{x}\right) \)[/tex]:

[tex]\[
\frac{0.5}{30} \cdot x^2 \cdot y \cdot \frac{x}{x^2} = y
\][/tex]


Sagot :

Sure! Let's solve this step-by-step.

1. Understand the given expression:

We have an expression:
[tex]\[ x^2 \cdot y \cdot \frac{x}{x^2} = y \][/tex]

Let's simplify the left-hand side of the expression.

2. Simplify the expression:

[tex]\[ x^2 \cdot y \cdot \frac{x}{x^2} \][/tex]

We can break down the fraction [tex]\(\frac{x}{x^2}\)[/tex]:
[tex]\[ \frac{x}{x^2} = \frac{1}{x} \][/tex]

Now substitute this back into the original expression:

[tex]\[ x^2 \cdot y \cdot \frac{1}{x} \][/tex]

Simplify further:
[tex]\[ x^2 \cdot \frac{1}{x} = x \Rightarrow x \cdot y = y \][/tex]

3. Thin simplifies to:

[tex]\[ x \cdot y \cdot \frac{1}{x} = y \][/tex]

This confirms our initial equality holds true in a more simple fashion.

4. Identify the target expression:

We need to find the value of the expression:
[tex]\[ x \cdot \frac{1}{x} \][/tex]

5. Simplify the target expression:

The expression [tex]\(x \cdot \frac{1}{x}\)[/tex] can be simplified as:
[tex]\[ x \cdot \frac{1}{x} = 1 \][/tex]

Hence, the value of [tex]\(x \cdot \frac{1}{x}\)[/tex] is:

[tex]\[ 1 \][/tex]

That is the final answer.
