Question:
The area of a rectangular computer chip is 112a^3b^2 square microns. Write a simplified expression that represents the length, if the width is 8ab
Answer:
[tex]Length = 14a^2b[/tex]
Step-by-step explanation:
Given
[tex]Area = 112a^3b^2[/tex]
[tex]Width = 8ab[/tex]
Required
Determine the height
Area is calculated as:
[tex]Area = Length * Width[/tex]
Make Length the subject
[tex]Length = \frac{Area}{Width}[/tex]
[tex]Length = \frac{112a^3b^2}{8ab}[/tex]
[tex]Length = \frac{14a^3b^2}{ab}[/tex]
Apply law of indices
[tex]Length = 14a^{3-1}b^{2-1}[/tex]
[tex]Length = 14a^2b[/tex]
