Question

It’s not 0.615 , or 0.75 or the one shown in the picture

Answer 1

`2.40714`

1) Let's evaluate that expression, given that a=4.9, b=-7, and c=-0.5

`\begin{gathered} a^3/ b^2+c^3 \\ (4.9)^3/(-7)^2+(-0.5)^3= \\ (4.9^3)/(\left(-7\right)^2+\left(-0.5\right)^3) \\ \\ (4.9^3)/(48.875) \\ \\ (117.649)/(48.875) \\ \\ 2.40714 \end{gathered}`

Note that we have rewritten it as a fraction so that we can easily operate. Also, we have applied here the PEMDAS order of operations, prioritizing the exponents.
