Question

C=\(\left(-2\right)^2\times\left|-\dfrac{1}{2}\right|-\sqrt{64}+\left(-5\right)^3\div5\)

Answer 1

\(C=\left(-2\right)^2\times\left|-\dfrac{1}{2}\right|-\sqrt{64}+\left(-5\right)^3:5\)

\(=4\times\dfrac{1}{2}-8+\left(-125\right):5\)

\(=2-8+\left(-25\right)\)

\(=\left(-6\right)+\left(-25\right)\)

\(=-31\)
