$\frac{\left(a+4\right)\sqrt{a-4}}{\sqrt{a+4}\sqrt{a-4}}\frac{\sqrt{a+4}}{\sqrt{a+4}}$
Learn how to solve factorization problems step by step online. Rationalize and simplify the expression ((a+4)(a-4)^(1/2))/((a+4)^(1/2)(a-4)^(1/2)). To rationalize the denominator of the fraction, we multiply the numerator and denominator by \sqrt{a+4}\sqrt{a-4}. Multiplying fractions \frac{\left(a+4\right)\sqrt{a-4}}{\sqrt{a+4}\sqrt{a-4}} \times \frac{\sqrt{a+4}}{\sqrt{a+4}}. When multiplying two powers that have the same base (\sqrt{a+4}), you can add the exponents. Simplify the fraction .
