Final answer:
To simplify the given expression 1+19-7)+7³ 8-2, we follow the order of operations or PEMDAS and get the simplified form as 346.
Step-by-step explanation:
To simplify the given expression, we follow the order of operations or PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).
First, we calculate the value inside the parentheses: 1+19-7 = 13.
Next, we calculate the exponent: 7³ = 7 * 7 * 7 = 343.
Finally, we perform the addition and subtraction: 13 + 343 - 8 - 2 = 346.
Therefore, the simplified expression is 346.
