If p and q are not 0, what is the value of \(p^3*q^3\) ?
1. \(p^2 – (\frac{4}{q})^2 = 0\)
2. \(p^3 – (\frac{4}{q})^3 = 0\)
Statement 1 :\(p^2=(\frac{4}{q})^2\) , multiply both sides of the equation by\(pq^3\)
\(p^3q^3=16pq\) we need the value of\(pq\) which cannot be determined by this equation. HenceInsufficient
Statement 2 \(p^3=(\frac{4}{q})^3\) . multiply both sides of the equation by\(q^3\)
\(p^3q^3=64\) Sufficient
OptionB
