To determine which number is the greatest, we need to compare the coefficients (the numbers before the "x 10") and ignore the exponents.

Comparing the coefficients:
a. 7.9
b. 9.8
c. 2
d. 4

The greatest coefficient is 9.8, so the number represented by option b. (9.8 x 10^-4) is the greatest.

To complete the problem, we need to determine the exponent in the scientific notation representation.

Given that 0.065 is equivalent to 6.5 x 10^x, we can determine the value of x by counting the number of decimal places we need to move to the right to convert 0.065 to 6.5.

In this case, we move the decimal point one place to the right, so x = -1.

Therefore, 0.065 = 6.5 x 10^-1.

To evaluate (73)8, we need to convert the number 73 from base 8 to base 10.

In base 8, each digit represents a multiple of a power of 8, starting from the rightmost digit. So, we can rewrite 73 as 7 * (8^1) + 3 * (8^0), which simplifies to 56 + 3 = 59 in base 10.

Therefore, (73)8 is equal to 59 in base 10.

Expanded form is a way of writing a number as the sum of its individual digit multiplied by their place value.

To express 5.5872 x 10^7 in expanded form, we can break it down as follows:

5.5872 x 10^7 = 5 * 10^7 + 0.5 * 10^7 + 0.08 * 10^7 + 0.007 * 10^7 + 0.0002 * 10^7

Simplifying further:

5 * 10^7 + 0.5 * 10^7 + 0.08 * 10^7 + 0.007 * 10^7 + 0.0002 * 10^7 = 50000000 + 5000000 + 800000 + 70000 + 2000

Therefore, the expanded form of 5.5872 x 10^7 is 50000000 + 5000000 + 800000 + 70000 + 2000.
