Introduction

In mathematics, exponents are a fundamental concept used to represent repeated multiplication of a number. The property $x^m \cdot x^n = x^{m+n}$ is a crucial rule that helps simplify expressions involving exponents. In this article, we will explore how to apply this property to determine the correct statement among the given options.

The Property: $x^m \cdot x^n = x^{m+n}$

The property $x^m \cdot x^n = x^{m+n}$ states that when we multiply two numbers with the same base, we can add their exponents. This property is a powerful tool for simplifying expressions and solving equations.

Applying the Property to the Given Options

Let's examine the given options and apply the property to determine the correct statement.

Option a) $(0.2)^3 \cdot (0.2)^5 = (0.2)^{3+5}$ or $(0.2)^3 \cdot (0.2)^5 = (0.2)^{3.5}$

To determine the correct statement, we can apply the property $x^m \cdot x^n = x^{m+n}$ . In this case, the base is $0.2$ , and the exponents are $3$ and $5$ . Using the property, we can add the exponents:

$(0.2)^3 \cdot (0.2)^5 = (0.2)^{3+5} = (0.2)^8$

This shows that the correct statement is $(0.2)^3 \cdot (0.2)^5 = (0.2)^{3+5}$ .

Option b) $(0.3)^6 = (0.3)^2 \cdot (0.3)^3 \quad$ or

To determine the correct statement, we can apply the property $x^m \cdot x^n = x^{m+n}$ . In this case, the base is $0.3$ , and the exponents are $2$ and $3$ . Using the property, we can add the exponents:

$(0.3)^2 \cdot (0.3)^3 = (0.3)^{2+3} = (0.3)^5$

This shows that the correct statement is $(0.3)^6 = (0.3)^2 \cdot (0.3)^3$ .

Conclusion

In conclusion, the property $x^m \cdot x^n = x^{m+n}$ is a powerful tool for simplifying expressions involving exponents. By applying this property, we can determine the correct statement among the given options. In this article, we have seen how to apply the property to options a) and b) and have determined the correct statements.
