Understanding the Concept of Like Bases

In mathematics, when we divide two expressions with the same base, we can simplify them using the quotient rule of exponents. The quotient rule states that when we divide two powers with the same base, we subtract the exponent of the divisor from the exponent of the dividend. In this article, we will explore how to divide expressions with like bases using the quotient rule.

Dividing Expressions with Like Bases: A Step-by-Step Guide

Example 1: Dividing 4246\frac{4^2}{4^6}

To divide 4246\frac{4^2}{4^6}, we can use the quotient rule of exponents. The quotient rule states that when we divide two powers with the same base, we subtract the exponent of the divisor from the exponent of the dividend. In this case, the base is 4, and the exponents are 2 and 6.

\frac{4^2}{4^6} = 4^{2-6} = 4^{-4}

Therefore, 4246=4−4\frac{4^2}{4^6} = 4^{-4}.

Example 2: Dividing 4−343\frac{4^{-3}}{4^3}

To divide 4−343\frac{4^{-3}}{4^3}, we can use the quotient rule of exponents. The quotient rule states that when we divide two powers with the same base, we subtract the exponent of the divisor from the exponent of the dividend. In this case, the base is 4, and the exponents are -3 and 3.

\frac{4^{-3}}{4^3} = 4^{-3-3} = 4^{-6}

Therefore, 4−343=4−6\frac{4^{-3}}{4^3} = 4^{-6}.

Example 3: Dividing 4−444\frac{4^{-4}}{4^4}

To divide 4−444\frac{4^{-4}}{4^4}, we can use the quotient rule of exponents. The quotient rule states that when we divide two powers with the same base, we subtract the exponent of the divisor from the exponent of the dividend. In this case, the base is 4, and the exponents are -4 and 4.

\frac{4^{-4}}{4^4} = 4^{-4-4} = 4^{-8}

Therefore, 4−444=4−8\frac{4^{-4}}{4^4} = 4^{-8}.

Conclusion

In conclusion, dividing expressions with like bases is a simple process that involves using the quotient rule of exponents. By subtracting the exponent of the divisor from the exponent of the dividend, we can simplify the expression and find the result. In this article, we have explored three examples of dividing expressions with like bases, and we have seen how the quotient rule can be used to simplify each expression.

Frequently Asked Questions

Q: What is the quotient rule of exponents?

A: The quotient rule of exponents states that when we divide two powers with the same base, we subtract the exponent of the divisor from the exponent of the dividend.

Q: How do I apply the quotient rule of exponents?

A: To apply the quotient rule of exponents, simply subtract the exponent of the divisor from the exponent of the dividend. For example, if we have 4246\frac{4^2}{4^6}, we would subtract 6 from 2 to get 42−6=4−44^{2-6} = 4^{-4}.

A: Yes, you can use the quotient rule of exponents with exponents with fractional exponents. For example, if we have 412432\frac{4^{\frac{1}{2}}}{4^{\frac{3}{2}}}, we would subtract 32\frac{3}{2} from 12\frac{1}{2} to get 412−32=4−14^{\frac{1}{2}-\frac{3}{2}} = 4^{-1}.

Q: What if I have a fraction with a negative fractional exponent?

A: If you have a fraction with a negative fractional exponent, you can still apply the quotient rule of exponents. For example, if we have 4−12432\frac{4^{-\frac{1}{2}}}{4^{\frac{3}{2}}}, we would subtract 32\frac{3}{2} from −12-\frac{1}{2} to get 4−12−32=4−24^{-\frac{1}{2}-\frac{3}{2}} = 4^{-2}.

Q: Can I use the quotient rule of exponents with exponents with complex numbers?

A: Yes, you can use the quotient rule of exponents with exponents with complex numbers. For example, if we have 4i4j\frac{4^i}{4^j}, we would subtract jj from ii to get 4i−j4^{i-j}.
