Answer:
Step-by-step explanation:
Since we see that 3/7 is multiplied by itself three times, we can use exponents as a shorter way to write this. The expontent tells us how many times the base number, 3/7, is multiplied by itself.
= 
We then multiply by -1 to (3/7)^3 to get the exact answer.
In 4 hours Zaps rental car charges $60 dollars and in 4 hours Easy car rental charges $59.5. So in 4 hours it is less expensive to rent from Easy car rental.
Answer:
6^ (-15) = x
Step-by-step explanation:
6^-8 = blank 6^7
6^-8 = x* 6^7
Divide each side by 6^7
6^-8 / 6^7 = x 6^7 / 6^7
6^-8 / 6^7 = x
Since the bases are the same, we can subtract the exponents
6^ ( -8-7) = x
6^ (-15) = x
Answer:
The required number is 7.
Dividing by this gives the perfect square 676.
Step-by-step explanation:
Finding the prime factors:
2) 4732
2) 2366
7) 1183
13)169
13
So 4372
= 2^2 * 7 * 13^2
= 4 *169 * 7
= 676 * 7
Now 676 is a perfect square so the answer is 7.
= 1283 * 4.
Answer is 1283.
The answer would be 6x+3y=2
