Answer:
Step-by-step explanation:
This problem is all about bases and exponents. Because we have a quotient and the bases are both 5's, that means that we can use the rule of exponents for quotients to rewrite and simplify:
That's the simplification as long as you are "allowed" to leave the exponent as a negative number.
The first one YES and the last one NO!
Answer: 6 miles
Step-by-step explanation:
The diameter is 2x the radius
2 x 3 = 6
2,000 is 10 times as much as 200. To find the answer we can divide 2,000 by 10:
2,000 / 10 = 200
It means that 200 is also 1/10 of 2,000.
If you want to find out what 2,000 is 1/10 of, then just multiply it by 10:
2,000 * 10 = 20,000
2,000 is 1/10 of 20,000.
