Question

Quizplus · Accepted Answer

When multiplying fractions, you multiply the numerators together and the denominators together. For the variables, you add the exponents when the bases are the same. Thus, $\left(\frac{1}{8} x^{5}\right)\left(\frac{1}{4} x^{7}\right) = \frac{1}{32} x^{12}$.

Multiply - (18x5)(14x7)\left(\frac{1}{8} x^{5}\right)\left(\frac{1}{4} x^{7}\right)(81​x5)(41​x7) A) 132x12\frac{1}{32} x^{12}321​x12 B) −132x12-\frac{1}{32} x^{12}−321​x12 C) 112x35\frac{1}{12} x^{35}121​x35
