Step-by-step explanation:
5^28 . 5^- 32 . 5^ -4
= 5^( 28 - 32 - 4 )
= 5^( 28 - 36 )
= 5^- 8
= 1 / 5^8
= 1 / 390625
= 0.000256
D 0.00000256
That would be B.
The set of points are all on the line which is a bisector.
lcd 210
1/5=42/210
1/7=30/310
3/21=30/210
42+30+30=102/210
reduced 51/105
1 miles= 1.609km
so, 25x1.609 = 40.225km
