Question 14
Algebraic ExpressionsIf p = (3/5)√(q/r), express q in terms of p and r.
- A.9/(25pr2)
- B.(9/25)p2r
- C.(25/9)p2r
- D.(25/9)pr2
Show the answer and explanation
Answer: C ((25/9)p2r)
Explanation
Square both sides: p2 = 9q/(25r), so q = 25p2r/9.
If p = (3/5)√(q/r), express q in terms of p and r.
Answer: C ((25/9)p2r)
Square both sides: p2 = 9q/(25r), so q = 25p2r/9.
