Answer:
18x²y²√6xy²
Step-by-step explanation:
3x∛648x⁴y⁸ = 3x ∛ 2 * 2 * 2 * 3 * 3 * 3 * 3 * x⁴ * y⁸
= 3x * 2 * 3 * x * y * y √2 * 3 * x * y * y
= 18x²y²√6xy²

The formula for compound interest is:
Step-by-step explanation:
This is an example of compound percentage increase.
To work this out, you would first have to convert the percentage into a decimal. You can do this by dividing the percentage of 3% by 100, this gives you 0.03. This is because percentages are out of 100 and so dividing the value by 100 gives you the percentage as a part of 1.
The next step is to add 1 to 0.03, this gives you 1.03. This is because you are working out the percentage increase.
The penultimate step is to work out the number of times that the new amount would need to be calculated. This can be done by multiplying 2 by 2, which gives you 4. This is because it will be compounded semiannually, which is twice a year.
The fnal step is to work out the total amount you would need to multiply the amount of 4,500 by 1.03 to the power of 4, this gives you 5064.79 (2 D.P). This is because you are working out 3% of the amount, and then adding it to the new amount and then finding 3% of that amount, and so on.
1) Divide 3% by 100.
2) Add 1 to 0.03.
3) Multiply 2 by 2.
4) Multiplly 4500 by 1.03 to the power of 4.
Nana's age: 10 years
Step-by-step explanation:
Here we call:
J = Jennifer's age
L = Laurel's age
N = Nana's age
We have the following information:
- Jennifer is twice as old as laurel, so
J = 2L (1)
- Laurel is 4 years younger than Nana, so
L = N - 4 (2)
- Nana is 2 years younger than Jennifer, so
N = J -2 (3)
Substituting (2) into (1),
J = 2(N-4) = 2N - 8
And substituting this into (3) and solving for J, we find Nana's age:
N = (2N-8) - 2
N = 2N - 10
N = 10
Which means that Jennifer's age is:
J = N + 2 = 12
And Laurel's age is
L = J/2 = 6
