Answer:
3^3×3
81
3^7/3^3
Explanation:
First you should solve the expression you've got there.
(3^6×3^-4)^2
3^6= 3×3×3×3×3×3 the answer is 729
3^-4 A negative exponent means repeated division by the base. So for example 2^-4=1/(2^4)
=1/(2×2×2×2)= 1/16
3^-4= 1/(3^4)
=1/(3×3×3×3)
= 1/81 If you look up the answer in your calculator the answer that will show up will be 0.01234567901
So!
(729×0.01234567901)^2= 9^2
9^2= 81
Now you can look at the following expressions and whichever gives the answer 81 will be correct.
hope it helps!

Explanation:</h2>
For inequalities, "a is no more than b" can be written as:
Here we know Candace that can spend no more than $52 before tax. She can spend a certain amount of money in both Dark Roast coffee and Morning Blend coffee. So she spends:
- 2 pounds of Morning Blend coffee.
- p pounds of Dark Roast coffee
Therefore:
<u>Amount of money for Morning Blend coffee:</u>
<u>Amount of money for Dark Roast coffee:</u>
So the total amount of money:
Finally, the inequality becomes:
Besides, in order to know how many pounds she can spend let's solve for p:
So she can spend less that 4.13 pounds.

Answer:
96
Step-by-step explanation:
If B is the midpoint of AC, the length of AC has to be twice the length of AB. This is because AB = AC. Twice 48 is 96.
The answer is 5.50h because h equals the hours and every hour u are receiving 5.50 so you will be multiplying
Here's a way to do it.
Let 4e +2 = 5n +1 . . . . . . for some integer n
Then e = (5n -1)/4 = n + (n -1)/4
We want (n-1)/4 to be an integer, so let it be integer m.
... m = (n -1)/4
... 4m = n -1
... 4m +1 = n
Substituting this into our expression for e gives
... e = (5(4m+1) -1)/4 = (20m +4)/4 = 5m +1
e = 5m+1 for any integer m
