The speed of light is expressed in scientific notation as 9.84times 10^8 feet per second. How is the speed of light in feet per second written in standard notation? A 984,000.000 B 9,840000,000 C 98.400,000,000 D 984,0 oo,ooo ,000 A B C D

The speed of light is given as $9.84 \times 10^8$ feet per second. The exponent 8 tells us to move the decimal point 8 places to the right.<br /><br />$9.84 \times 10^8 = 984000000$<br /><br />So, the speed of light in standard notation is 984,000,000 feet per second.<br /><br />Therefore, the correct answer is $\boxed{A}$.<br />
