Q. What is the value of z in equation z = 7x (y2) when x = 4 and y = 2:
(A) 56
(B) 112
(C) 116
(D) None of these
Bonus Solution:
We are given the equation:
Z = 7x (y2)
Substitute the values x=4 and y=2:
Z = 7 (4) (22)
Now, calculate 22:
22=4
So, the equation becomes:
Z =7 (4) (4)
Now, multiply:
Z = 7 × 4 × 4 = 7 × 16 = 112
