Simplify the following expression:
[tex]\[
\frac{y^2 z^6}{y^3 z^5}
\][/tex]


Sagot :

To simplify the given expression [tex]\(\frac{y^2 z^6}{y^3 z^5}\)[/tex], we will use the properties of exponents. Let's break it down step by step:

1. Separate the expression into parts involving [tex]\(y\)[/tex] and [tex]\(z\)[/tex]:

[tex]\[ \frac{y^2 z^6}{y^3 z^5} = \frac{y^2}{y^3} \cdot \frac{z^6}{z^5} \][/tex]

2. Simplify the part involving [tex]\(y\)[/tex]:

When dividing expressions with the same base, we subtract the exponent in the denominator from the exponent in the numerator:

[tex]\[ \frac{y^2}{y^3} = y^{2-3} = y^{-1} \][/tex]

3. Simplify the part involving [tex]\(z\)[/tex]:

Similarly, when dividing expressions with the same base, we subtract the exponent in the denominator from the exponent in the numerator:

[tex]\[ \frac{z^6}{z^5} = z^{6-5} = z^1 = z \][/tex]

4. Combine the simplified parts:

Now, we combine the simplified expressions for [tex]\(y\)[/tex] and [tex]\(z\)[/tex]:

[tex]\[ y^{-1} \cdot z \][/tex]

5. Convert negative exponents to fractions:

A negative exponent indicates the reciprocal of the base with the positive exponent. Therefore,

[tex]\[ y^{-1} = \frac{1}{y} \][/tex]

6. Write the final simplified expression:

Using the reciprocal property for [tex]\(y^{-1}\)[/tex], we multiply it by [tex]\(z\)[/tex]:

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

Therefore, the simplified expression is:

[tex]\[ \frac{z}{y} \][/tex]
