Question

Write the expression (-7) - (-7) · 5-5-5.5 using exponents.

Answer 1

To write the expression (-7) - (-7) · 5-5-5.5 using exponents, follow the order of operations and simplify the expression step by step, resulting in -10.5.

Step-by-step explanation:

To write the expression (-7) - (-7) · 5-5-5.5 using exponents, we first need to follow the order of operations as defined in mathematics. Exponents are typically done after multiplication and division, but before addition and subtraction. In this case, there are no exponents involved. So, we can simplify the expression step by step:

1. First, let's deal with the subtraction inside the parentheses: (-7) - (-7) = -7 + 7 = 0
2. Next, we perform the multiplication: 0 · 5 = 0
3. Then, we subtract 5: 0 - 5 = -5
4. Finally, we subtract 5.5 from -5: -5 - 5.5 = -10.5

Therefore, the expression (-7) - (-7) · 5-5-5.5 is equal to -10.5.
