Final answer:
To simplify the expression, follow the order of operations (PEMDAS). Simplify the expression inside the parentheses first, then perform any exponentiation. Finally, combine all the terms to get the simplified result.
Step-by-step explanation:
To simplify the expression -15+(-1.6+9.34/6) •3^2 - 5.7, we need to follow the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).
First, let's simplify the expression inside the parentheses: -1.6+9.34/6. To do this, we divide 9.34 by 6 and then add -1.6. The result is 0.62333.
Next, we simplify the expression -15+0.62333 •3^2 - 5.7. Expanding the exponent, we get -15+0.62333 • 9 - 5.7. Multiplying 0.62333 by 9, we get 5.60997. Finally, we combine all the terms: -15 + 5.60997 - 5.7 = -15 + 5.60997 - 5.7 = -15 - 0.09003 = -15.09003.
