Using the power law (x^27 ⋅ y)^1/3 equals x^9 ⋅ x^1/3.
Raising a number to the 1/3 is the same as cube rooting.
So the simplified response is x^9(cube root of y).
answer: 2nd choice
Answer:
Estimated time = 490 seconds
Exact time = 463.98 seconds
Step-by-step explanation:
The car traveled 1 mile in 70.3 seconds.
We want to find how long it took to travel 6.6 miles.
We are told to estimate the given values to the nearest whole numbers before solving.
Thus;
1 mile was travelled in 70 seconds
Then; 6.6 miles ≈ 7 miles
Thus, 7 miles is travelled in; 70 × 7/1 = 490 seconds
Estimated time = 490 seconds
Now, exact time will be;
Exact time = 70.3 × 6.6/1
Exact time = 463.98 seconds
