Which of the following expressions can be simplified to give an answer of 1?

Question

15 - (9.1)^0
2 (8^0)
11^0 + 24^0
(-5.22)^0

Answer 1

Let's simplify each of the expressions to determine which of them can be simplified to give an answer of 1.

1. 15 - (9.1)^0
   \((9.1)^0 = 1\)
   So, \(15 - 1 = 14\)

2. 2 (8^0)
   \((8^0 = 1)\)
   So, \(2 \times 1 = 2\)

3. 11^0 + 24^0
   \((11^0 = 1)\) and \((24^0 = 1)\)
   So, \(1 + 1 = 2\)

4. (-5.22)^0
   \((-5.22)^0 = 1\)

Now let's summarize the results:

• The first expression simplifies to 14.
• The second expression simplifies to 2.
• The third expression simplifies to 2.
• The fourth expression simplifies to 1.

Based on this analysis, the expressions that simplify to give an answer of 1 are:

• (-5.22)^0

Thus, the answer is: (-5.22)^0.
