1 answer

To compare the numbers using scientific notation, we first convert each number to scientific notation:

  1. 12,740,876,635

    • This can be expressed as \(1.2740876635 \times 10^{10}\).
  2. 1,345,763,334

    • This can be expressed as \(1.345763334 \times 10^9\).
  3. 12,920,370,000

    • This can be expressed as \(1.292037 \times 10^{10}\).

Now, let's summarize them in scientific notation:

  • \(12,740,876,635 = 1.2740876635 \times 10^{10}\)
  • \(1,345,763,334 = 1.345763334 \times 10^{9}\)
  • \(12,920,370,000 = 1.292037 \times 10^{10}\)

Next, we compare their exponents and coefficients:

  • The first number: \(1.2740876635 \times 10^{10}\) has an exponent of \(10\).
  • The second number: \(1.345763334 \times 10^{9}\) has an exponent of \(9\), which means it is smaller than both others.
  • The third number: \(1.292037 \times 10^{10}\) also has an exponent of \(10\).

Now, we only need to compare \(1.2740876635\) and \(1.292037\):

  • \(1.2740876635 < 1.292037\)

Thus, among the numbers:

  • \(12,740,876,635 (1.2740876635 \times 10^{10})\) is less than \(12,920,370,000 (1.292037 \times 10^{10})\).
  • Finally, \(1,345,763,334 (1.345763334 \times 10^{9})\) is the smallest because its exponent is \(9\).

The greatest value among the three numbers is 12,920,370,000.
