Question

CHOOSE TWO. Which two of the following choices express the same value and are both written properly?

8.81 x 102

0.0881

881

88.1 x 101

88.1 x 10-2

8.81 x 10-3

88,100

Answer 1

To determine which two of the choices express the same value, let's convert each of them to standard decimal form.

1. **8.81 x 10^2** = 881.0
2. **0.0881** = 8.81 x 10^-2
3. **881** = 881.0
4. **88.1 x 10^1** = 881.0
5. **88.1 x 10^-2** = 0.881
6. **8.81 x 10^-3** = 0.00881
7. **88,100** = 88.1 x 10^3

Now, let's identify pairs that express the same value:

- **8.81 x 10^2** = 881
- **88.1 x 10^1** = 881

Thus, the two choices that express the same value are:

- **8.81 x 10^2**
- **881**

So, the answer is:
1. **8.81 x 10^2**
2. **881**
