If \(8^c \cdot\sqrt8=\dfrac{8^a}{8^b}\) then \(a = ?\)

A. \(b\left(\dfrac12 + c\right)\)

B. \(\dfrac{bc}2\)

C. \(\dfrac{b + c}2\)

D. \(2b + c\)

E. \(\dfrac12 + b + c\)

Answer: E

\(8^c\) . \(\sqrt{8}\) = \(8^{\left(c+\frac{1}{\left(2\right)}\right)}\)
Likewise, \(8^a\) / \(8^b\) = \(8^{a-b}\)
Thus, c+1/2=a-b
or a = b+c+1/2

Option E
