ok sweetheart so basicaly what u do is...
Sample Response: Each base must be treated separately. Since each base is raised to a negative exponent, they should both be in the denominator of the fractions. The simplified form of the expression has 1 in the numerator and r to the 8th power times s to the 5th power in the denominator
(6x4)(4x3)
Hope this helps you. I accidentally wrote my answer in the comment box.

Answer/Step-by-step explanation:
#8. Using the geometric mean theorem formula, h = √xy, where,
h = x
x = 4 and y = 16
Plug in the values
x = √(4*16)
x = 8
#9. Using the geometric mean formula, h = √xy, where,
h = y
x = 5 and y = 8
Plug in the values into the formula:
y = √(5*8)
y = √40
y = 6.3 (nearest tenth)
#10. Using the geometric mean formula, h = √xy, where,
h = 18
x = 12 and y = y = ???
Plug in the values into the formula:
18 = √(12*y)
Square both sides
18² = 12y
324 = 12y
Divide both sides by 12
27 = y
y = 27
The number you thought of was 5
Step-by-step explanation:
You thought of a number
- Doubled it
- Then added 3
- The result multiplied 4
- The answer was 52
Assume that the number was x
∵ The number = x
∵ The number was doubled
- Double means multiply it by 2
∴ The result = 2x
∵ You added 3
∴ The sum = 2x + 3
∵ You multiplied the sum by 4
∴ The product = 4(2x + 3)
∵ It came 52
∴ 4(2x + 3) = 52
- Simplify it
∴ 4(2x) + 4(3) = 52
∴ 8x + 12 = 52
- Subtract 12 from both sides
∴ 8x = 40
- Divide both sides by 8
∴ x = 5
The number you thought of was 5
