Answer:
19 cents
Step-by-step explanation:
divide 20 by 6
Answer:
When multiplying the same number, raised to different powers, you carry the number forward so (2/7)^6 is part of the answer.
Now, we have to calculate the exponent.
2x + 1 = 6
So, the answer is x = 2.5 which means
[2/7]^(2*2.5) x [2/7]^1 = [2/7]^6 which equals
[2/7]^5 x [2/7]^1 = [2/7]^6
