about how far can light travel in 1 year? remember there are 3.15576×10^7 seconds in a single year. lets make a reasonable estimate. what is (3×10^8)×(3×10^7)? (3×10^8)×(3×10^7) meters per year = (3×3)×(10^8×10^7) meters per year =?×10^? meters per year light travels at a speed of 299,792,458 meters per second. thats about 3×10^8 meters per second.

Answer

Explanation:

Step1: Multiply the non - exponential parts

$3\times3 = 9$

Step2: Multiply the exponential parts using the rule $a^m\times a^n=a^{m + n}$

$10^{8}\times10^{7}=10^{8 + 7}=10^{15}$

Answer:

$9\times10^{15}$
