Question

7+[-8-5^2]/(1-4)^3+17

Answer 1

2.6

Explanations:

Given the expression;

`(7+\lbrack-8-5^2\rbrack)/((1-4)^3+17)`

Simplify the expression in the bracket to have:

`\begin{gathered} =(7+\lbrack-8-25\rbrack)/((-3)^3+17) \\ =(7+(-33))/((-3*-3*-3)+17) \\ =(7+(-33))/(-27+17) \end{gathered}`

Simplify the result to have;

`\begin{gathered} =(7-33)/(-10) \\ =(-26)/(-10) \\ =2.6 \end{gathered}`

Hence the result of the given function on simplification is 2.6
