Verified Answer :

So you have to Divide 21/7 which = 3 then you multiply 3*6^2 which is 108 then add 3 which equals A) 111.

Answer:

The correct option is a) 111.

Step-by-step explanation:

Consider the provided expression.

\(\frac{a}{z}+bw^2\)

Substitute the value of a=21, b=3, w=6 and z=7 in the above expression and solve.

\(\frac{21}{7}+(3)(6)^2\)

\(3+(3)(36)\)

\(3+108\)

\(111\)

Hence, the value of the expression for a=21, b=3,w=6 and z=7 is 111.

Thus, the correct option is a) 111.
