1.2740635 x 10^7 < 1.292037 x 10^7 < 1.345763334 x 10^9
Therefore, the number in option B) 1.292037 x 10^10 has the greatest value.
To compare these numbers in scientific notation, we need to convert each of them to scientific notation.
The scientific notation is written in the form of A x 10^B, where A is a number between 1 and 10, and B is an integer.
Let's convert each number:
12,740,635 = 1.2740635 x 10^7
1,345,763,334 = 1.345763334 x 10^9
12,920,370 = 1.292037 x 10^7
Now, let's compare the numbers:
A) 1.2740876635 x 10^10
B) 1.292037 x 10^10
C) 12,920,370,000
D) 1.345763334

Therefore, option B) 1.292037 x 10^10 has the greatest value.
To compare these numbers using scientific notation, we need to rewrite them in the same format. Here are the numbers in scientific notation:
A) 1.2740876635 x 10^10
B) 1.292037 x 10^10
C) 1.292037 x 10^10
D) 1.345763334
Now, let's compare the numerical values:
A) 1.2740876635 x 10^10
B) 1.292037 x 10^10
Since both A and B have the same power of 10, we can compare the numerical values directly. The numerical value of A is 1.2740876635, and the numerical value of B is 1.292037.
Since 1.292037 is greater than 1.2740876635, B has the greater value.
Therefore, the option with the greatest value is option B) 1.292037 x 10^10.
