Which Term Is A Perfect Square Of The Root 3 X 4 3x^4 3 X 4 ?A. 6 X 8 6x^8 6 X 8 B. 6 X 16 6x^{16} 6 X 16 C. 9 X 8 9x^8 9 X 8 D. 9 X 16 9x^{16} 9 X 16
Introduction
In mathematics, a perfect square is a number that can be expressed as the square of an integer. For example, 16 is a perfect square because it can be expressed as 4^2. In algebra, we can also have perfect squares of variables and expressions. In this article, we will explore which term is a perfect square of the root .
Understanding Perfect Squares
A perfect square is a number or expression that can be expressed as the square of another number or expression. For example, (2x)^2 is a perfect square because it can be expressed as 4x^2. To find the perfect square of an expression, we need to multiply the expression by itself.
Finding the Perfect Square of
To find the perfect square of , we need to multiply it by itself. This means we need to multiply by .
Step 1: Multiply by
To multiply by , we need to follow the rules of exponentiation. When we multiply two variables with the same base, we add their exponents. In this case, we have:
(3x^4) * (3x^4) = 3 * 3 * x^4 * x^4 = 9 * x^(4+4) = 9 * x^8
Step 2: Simplify the Expression
The expression 9 * x^8 is already simplified. We can see that it is a perfect square of the root .
Conclusion
In conclusion, the perfect square of the root is 9 * x^8. This means that option C, 9x^8, is the correct answer.
Comparison of Options
Let's compare the options:
A. 6x^8: This option is not a perfect square of the root because it does not have the same base and exponent as the original expression.
B. 6x^16: This option is not a perfect square of the root because it has a different base and exponent than the original expression.
C. 9x^8: This option is a perfect square of the root because it has the same base and exponent as the original expression.
D. 9x^16: This option is not a perfect square of the root because it has a different base and exponent than the original expression.

Q: What is a perfect square?
A: A perfect square is a number or expression that can be expressed as the square of another number or expression. For example, (2x)^2 is a perfect square because it can be expressed as 4x^2.
Q: How do I find the perfect square of an expression?
A: To find the perfect square of an expression, you need to multiply the expression by itself. For example, to find the perfect square of , you would multiply it by itself: (3x^4) * (3x^4) = 9 * x^8.
Q: What is the difference between a perfect square and a perfect cube?
A: A perfect square is a number or expression that can be expressed as the square of another number or expression. A perfect cube is a number or expression that can be expressed as the cube of another number or expression. For example, (2x)^3 is a perfect cube because it can be expressed as 8x^3.
Q: Can a perfect square have a negative exponent?
A: Yes, a perfect square can have a negative exponent. For example, (2x)^(-2) is a perfect square because it can be expressed as 1/(4x^2).
Q: How do I simplify a perfect square expression?
A: To simplify a perfect square expression, you need to follow the rules of exponentiation. When you multiply two variables with the same base, you add their exponents. For example, (3x^4) * (3x^4) = 9 * x^8.
Q: Can a perfect square have a fractional exponent?
A: Yes, a perfect square can have a fractional exponent. For example, (2x)^(1/2) is a perfect square because it can be expressed as sqrt(2x).
Q: How do I find the square root of a perfect square expression?
A: To find the square root of a perfect square expression, you need to take the square root of the expression. For example, the square root of (3x4)2 is 3x^2.
Q: Can a perfect square have a complex number as its base?
A: Yes, a perfect square can have a complex number as its base. For example, (2+3i)^2 is a perfect square because it can be expressed as (2+3i)(2+3i).
Conclusion
In conclusion, perfect squares and roots are an important concept in mathematics. By understanding how to find perfect squares and simplify expressions, you can solve a wide range of mathematical problems.
