If x * y = (x + 3)2 (y - 1), then the value of 5 * 4 is?
A. 192
B. 182
C. 180
D. 172
Answer: Option A
Solution(By Examveda Team)
$$\eqalign{ & x*y = {\left( {x + 3} \right)^2}\left( {y - 1} \right) \cr & \Leftrightarrow 5*4 = {\left( {5 + 3} \right)^2}\left( {4 - 1} \right) \cr & \Leftrightarrow 5*4 = 64 \times 3 \cr & \Leftrightarrow 5*4 = 192 \cr} $$Related Questions on Algebra
