By virtue of law of indices
(3^2)^-8 × (3^3)^-2
3^-16 × 3^-6
3^(-16+(-6))
3^(-16-6)
3-²²
= 1/3²²
Answer:
yes
Step-by-step explanation:
not sure how to explain it's kinda hard sorry
The price per ounce for the 14.2 ounce bottle is $0.28. The price per ounce for the 33.9 ounce bottle is $0.29. Therefore, the 14.2 ounce bottle of shampoo Is the better buy.
You take the total price of the shampoo bottle and divide it by how many ounces there are to get the price per ounce.
P.s. it says I’m a beginner because I made a new account
let's find the area of the outer circle and the inside circle
the inside's circle area
A= π x 6²=36π
the outer's
A' = π x 4x²= 4πx²
A'-A=4πx²- 36π=160πcm² equivalent to x²- 9=40, so x²=49 implies x =sqrt(49)=7, x=7.
First, change the mixed fraction into improper fraction
1 1/7 = 7/7 + 1/7 = 8/7
(4/7)/(8/7)
To solve, flip the second fraction, and change the division into multiplication
(4/7)/(8/7) = (4/7) x (7/8)
Multiply, and simplify
(4/7) x (7/8) = 28/56, or 1/2
1/2 is your answer
hope this helps
