Answer:
21 times 21
Step-by-step explanation:
Do you mean 9^2 ⋅ 9^6 ???
If so
9^2 ⋅ 9^6 = 9^(2+6) = 9^8
Also
9^10 / 9^2 = 9^(10 - 2) = 9^8
Answer:
9 to the 10th power over 9 to the 2nd power would be equivalent to 9^2 ⋅ 9^6
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
Answer:
D
Step-by-step explanation:
So first you simplify
Step 1: (2•3•7x3y6) (2•3xy6)
Step 2: you divide x3 by x1 = x (3-1) = x2
step 3: You cancel out y6 as it appears on both sides of the fraction line.
step 4: cancel out 2 as it appears on both sides.
step 5: cancel out 3 as it appears on both sides.
step 6: final result 7x2
