Introduction

Algebraic expressions can be complex and daunting, but with the right rules and techniques, they can be simplified to reveal their underlying structure. In this article, we will explore how to simplify two algebraic expressions using specific rules. We will examine each expression, identify the relevant rule, and apply it to simplify the expression.

Expression 1: $3\left(\frac{2}{x^{1 / 2}}\right)^4$

Applying the Power Rule for Fractions

The first expression is $3\left(\frac{2}{x^{1 / 2}}\right)^4$ . To simplify this expression, we need to apply the power rule for fractions, which states that $\left(\frac{a}{b}\right)^n=\frac{a^n}{b^n}$ . This rule allows us to raise the numerator and denominator of a fraction to a power.

\left(\frac{2}{x^{1 / 2}}\right)^4 = \frac{2^4}{(x^{1 / 2})^4}

Simplifying the Expression

Now that we have applied the power rule, we can simplify the expression further. We can evaluate the exponent on the numerator and denominator.

\frac{2^4}{(x^{1 / 2})^4} = \frac{16}{x^2}

Final Answer

The simplified expression is $\frac{16}{x^2}$ .

Expression 2: $\left(x^{1 / 2} y\right)^2$

Applying the Power Rule for Products

The second expression is $\left(x^{1 / 2} y\right)^2$ . To simplify this expression, we need to apply the power rule for products, which states that $(ab)^n=a^nb^n$ . This rule allows us to raise a product to a power.

\left(x^{1 / 2} y\right)^2 = (x^{1 / 2})^2(y)^2

Simplifying the Expression

Now that we have applied the power rule, we can simplify the expression further. We can evaluate the exponent on the numerator and denominator.

(x^{1 / 2})^2(y)^2 = x y^2

Final Answer

The simplified expression is $x y^2$ .
