Question 12
Algebraic ExpressionsIf P = √(rs3/t), express r in terms of p, s and t.
- A.p2t/s3
- B.p3t/s3
- C.p3t/s2
- D.pt/s3
Show the answer and explanation
Answer: A (p2t/s3)
Explanation
Square both sides: P2 = rs3/t, so r = P2t/s3.
If P = √(rs3/t), express r in terms of p, s and t.
Answer: A (p2t/s3)
Square both sides: P2 = rs3/t, so r = P2t/s3.
