Final answer:
To express the given expression as a decimal, we need to evaluate the numerical part of the expression first. Following the order of operations, we find that the expression simplifies to 9.
Step-by-step explanation:
To express the given expression as a decimal, we need to evaluate the numerical part of the expression first. Following the order of operations, we start with the inner parentheses:
(8)/(4)-(2-9) ⁽⁻¹⁾ = (8)/(4)-(-7)
Next, we can simplify the expression:
(8)/(4)-(-7) = 2-(-7)
Simplifying further:
2-(-7) = 2+7
The final answer is:
2+7 = 9
Therefore, the expressed decimal is 9.
