Answer:c) To write 2,400,000 in standard form, we need to express it as a number between 1 and 10 multiplied by a power of 10. We can do this by counting the number of zeros after the 4 in 2,400,000, which gives us 6 zeros. Therefore, we can write 2,400,000 in standard form as 2.4 x 10^6.
d) To write 0.00147 in standard form, we need to express it as a number between 1 and 10 multiplied by a power of 10. We can do this by counting the number of places we need to move the decimal point to the right until we get a number between 1 and 10. In this case, we need to move the decimal point 3 places to the right, giving us 1.47. Since we moved the decimal point 3 places to the right, we need to multiply by 10^-3. Therefore, 0.00147 can be written in standard form as 1.47 x 10^-3.
