14. Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approximately 5.88x10 miles. Suppose a star is 2 23x 10 light- years from Earth. In scientific notation, approximately how many miles is it?

Question

A)2.23X10^14
B)1.31X10^14
C)1.13X10^15
D)5.88X10^12

Answer 1

Your information is incorrect:
1 light-year = 5.879 x 10^12 miles or 9.461 x 10^14 km

"Suppose a star is 2 23x 10 light- years from Earth"
is there supposed to be a decimal in 2 23 ?
is there an exponent 10^?

once you have that fixed, multiply your (2 23x 10) by 5.879 x 10^12 miles
