Question

Simplify the expression -15 + (-16 + 9.34/6) •3^2 -5.7

Answer 1

`\Huge \boxed{\boxed{\bf{-150.69}}}`

Explanation:

To simplify the expression, we can follow the order of operations (also known as PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication/Division, and Addition/Subtraction.

`\Large \boxed{\bf{-15 + (-16 + 9.34/6) * 3^2 - 5.7}}`

First, let's simplify the expression inside the parentheses:

• 
  `\tt{-15 + (-16 + 1.55666666667) * 3^2 - 5.7}`

Next, let's simplify the exponent:

• -
  `\tt{15 + (-16 + 1.55666666667) * 9 - 5.7}`

Now, let's simplify the addition and subtraction within the parentheses:

• 
  `\tt{-15 + (-14.4433333333) * 9 - 5.7}`

Next, let's perform the multiplication:

• 
  `\tt{-15 + (-129.99) - 5.7}`

Now, let's perform the addition and subtraction from left to right:

• 
  `\tt{-144.99 - 5.7}`

Finally, subtract the two numbers:

• 
  `\tt{-150.69}`

Therefore, the simplified expression is -150.69.
