Answer 1

Given:

The given expression is

`\begin{gathered} √(a^3-7)+|b|. \\ \text{ And }a=2,\text{ }b=-4. \end{gathered}`

Required:

We have to find the value of the given expression from the given value of a and b.

Step-by-step explanation:

We put the given value of a and b in the given expression to find the answer.

`\begin{gathered} √((2)^3-7)+|-4| \\ =√(8-7)+4 \end{gathered}`
`\begin{gathered} =1+4 \\ =5. \end{gathered}`
