Understanding the Concept of Exponent Zero

In mathematics, the concept of exponent zero is a fundamental rule that helps simplify expressions. When an expression is raised to the power of zero, it is equal to 1, unless the base is zero. In this case, we have the expression $-3\left(2 x^5 y^3 z^4\right)^0$ . Our goal is to simplify this expression using the concept of exponent zero.

Applying the Rule of Exponent Zero

The rule of exponent zero states that any non-zero number raised to the power of zero is equal to 1. In this case, the base is $2 x^5 y^3 z^4$ , which is a non-zero expression. Therefore, we can apply the rule of exponent zero to simplify the expression.

Simplifying the Expression

Using the rule of exponent zero, we can simplify the expression as follows:

$-3\left(2 x^5 y^3 z^4\right)^0 = -3 \cdot 1 = -3$

Explanation

In the expression $-3\left(2 x^5 y^3 z^4\right)^0$ , the exponent zero is applied to the base $2 x^5 y^3 z^4$ . Since the base is non-zero, we can apply the rule of exponent zero, which states that any non-zero number raised to the power of zero is equal to 1. Therefore, we can simplify the expression by replacing the base with 1.

Conclusion

In conclusion, the expression $-3\left(2 x^5 y^3 z^4\right)^0$ can be simplified using the concept of exponent zero. By applying the rule of exponent zero, we can simplify the expression to $-3$ . This demonstrates the importance of understanding the concept of exponent zero in simplifying mathematical expressions.
