I was given this to evaluate: $\displaystyle 6\bigg(1\frac{7}{16}\bigg)^{\frac{1}{2}}\times 2^{1}$. When finished, I got my final answer as 4. Is it correct? How do I check whether my answer is correct or wrong in such simplification or evaluation?

Yep. I got 4 (eventually). I'd check it on a calculator or computer.
