The equation that is correct is 11.11 = 11² = 121. The correct answer is the fourth option: 11 dot 11 equals 11 Superscript 2 equals 121 (11.11 = 11² = 121)
From the question,
We are to determine which of the options is correct.
To determine which of the options is correct, we will evaluate the options one after the other.
- For the first option
8 dot 8 equals 8 Superscript 2 equals 16
That is,
8.8 = 8² = 16
Evaluating properly
8.8 = 8² = 8 × 8 = 64
Then, 8.8 = 8² ≠ 16
∴ This is NOT correct
- For the second option
9 dot 9 equals 2 left-parenthesis 9 right-parenthesis equals 18
That is,
9.9 = 2(9) = 18
Evaluating properly
9.9 = 9 × 9 = 9² = 81
Then, 9.9 ≠ 2(9) = 18
∴ This is NOT correct
- For the third option
10 dot 10 equals 2 left-parenthesis 10 right-parenthesis equals 100
That is,
10.10 = 2(10) = 100
Evaluating properly
10.10 = 10 × 10 = 10² = 100
Then, 10.10 ≠ 2(10) ≠ 100
∴This is NOT correct
- For the fourth option
11 dot 11 equals 11 Superscript 2 equals 121
That is,
11.11 = 11² = 121
Evaluating properly
11.11 = 11² = 11 × 11 = 121
Then, 11.11 = 11² = 121
This is correct.
Hence, the equation that is correct is 11.11 = 11² = 121. The correct answer is the fourth option: 11 dot 11 equals 11 Superscript 2 equals 121 (11.11 = 11² = 121)
