Perform the Indicated Operation Involving Rational Expressions $\frac { 8 x ^ { 9 } y ^ { 9 } } { 9 x ^ { 10 } y ^ { 8 } } \cdot \frac { 63 x ^ { 9 } } { 64 y } \cdot \frac { 8 x } { y ^ { 8 } }$

question 228

Short Answer

Perform the indicated operation involving rational expressions. Express final answer in simplest form. $\frac { 8 x ^ { 9 } y ^ { 9 } } { 9 x ^ { 10 } y ^ { 8 } } \cdot \frac { 63 x ^ { 9 } } { 64 y } \cdot \frac { 8 x } { y ^ { 8 } }$

Definitions:

Scatter Plot

A diagram that shows the relationship between two variables by displaying points on a two-dimensional plot. Usually the two variables are denoted x and y, each point represents a pair of scores, and the x variable is plotted on the horizontal axis while the y variable is plotted on the vertical axis.

Upward Slope

A term that can be used metaphorically to describe a situation or trend that is improving or increasing over time.

Replication

Doing a study again to see if the results hold up. Replications are especially persuasive when done by different researchers in different labs than the original study.

Stability of Results

The consistency of outcomes or findings over time in experiments, studies, or measurements, indicating reliability.
