Question

0.6 + 0.05 + 0.009 in standard form is:

a) 0.659 × 10^0

b) 6.59 × 10^-1

c) 6.59 × 10^0

d) 659 × 10^-3

Answer 1

To express the sum of 0.6 + 0.05 + 0.009 in standard form, we add the numbers together and write it in scientific notation by moving the decimal point to the right until there is a single non-zero digit to the left of the decimal point. The answer is 6.59 x 10^0.

Step-by-step explanation:

To express the sum of 0.6 + 0.05 + 0.009 in standard form, we add the numbers together: 0.6 + 0.05 + 0.009 = 0.659. We then write it in scientific notation by moving the decimal point to the right until there is a single non-zero digit to the left of the decimal point, and counting the number of decimal places we moved the point. In this case, we moved the decimal point one place to the right, so the answer is 6.59 x 10^0.

Therefore, the correct answer is (c) 6.59 x 10^0.
