Simplify The Expression.What Is The Simplest Form Of $\sqrt{324 A^2 B^6}$?(Assume That $a \geq 0$ And $b \geq 0$.)

Introduction

Simplifying radical expressions is a crucial skill in mathematics, particularly in algebra and geometry. It involves expressing a given expression in its simplest form, which can be achieved by factoring out perfect squares and simplifying the remaining terms. In this article, we will focus on simplifying the expression $\sqrt{324 a^2 b^6}$, assuming that $a \geq 0$ and $b \geq 0$.

Understanding Radical Expressions

A radical expression is a mathematical expression that contains a square root or a higher-order root. The square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 16 is 4, because 4 multiplied by 4 equals 16. Similarly, the square root of 25 is 5, because 5 multiplied by 5 equals 25.

Simplifying the Expression

To simplify the expression $\sqrt{324 a^2 b^6}$, we need to factor out perfect squares and simplify the remaining terms. We can start by breaking down the expression into its prime factors.

Prime Factorization

The prime factorization of 324 is $2^2 \times 3^4$. Therefore, we can write the expression as:

$$\sqrt{324 a^2 b^6} = \sqrt{2^2 \times 3^4 \times a^2 \times b^6}$$

Factoring Out Perfect Squares

Now, we can factor out perfect squares from the expression. We can see that $2^2$, $a^2$, and $b^6$ are perfect squares. Therefore, we can write the expression as:

$$\sqrt{2^2 \times 3^4 \times a^2 \times b^6} = 2 \times 3^2 \times a \times b^3 \times \sqrt{3^2 \times b^2}$$

Simplifying the Remaining Terms

Now, we can simplify the remaining terms. We can see that $3^2$ and $b^2$ are perfect squares. Therefore, we can write the expression as:

$$2 \times 3^2 \times a \times b^3 \times \sqrt{3^2 \times b^2} = 2 \times 9 \times a \times b^3 \times 3 \times b = 54 a b^4$$

Final Answer

Therefore, the simplest form of $\sqrt{324 a^2 b^6}$ is $54 a b^4$.

Conclusion

Simplifying radical expressions is a crucial skill in mathematics, particularly in algebra and geometry. By factoring out perfect squares and simplifying the remaining terms, we can express a given expression in its simplest form. In this article, we have focused on simplifying the expression $\sqrt{324 a^2 b^6}$, assuming that $a \geq 0$ and $b \geq 0$. We have shown that the simplest form of the expression is $54 a b^4$.
