When you have a negative exponent, you move the variable with the negative exponent to the other side of the fraction to make the exponent positive.
For example:
or
(you don't move the "2" because "2" has an exponent of 1, only "y" has the negative exponent)
When you multiply a variable with an exponent by a variable with an exponent, you add the exponents together. (But you can only combine the exponents when the variables are the same)
(You can't combine them because they have different variables of x and y)
There's two ways you can do this. Either by first making all the exponents positive then do subtraction, or multiply them then make all the exponents positive. I'm doing the 2nd way.
You can combine the numbers 2 x 9 x 2 = 36
Now multiply the terms with the same variables
Now make all the exponents positive
If you were to do subtraction, here is what you need to know:
When you divide a variable with an exponent by a variable with an exponent, you subtract the exponents together. (Reminder: they have to be the same variable in order to combine the exponents)
For example:
or x
Answer:
Account B is the better choice for earning her (6751.25 - 6710) = $41.25 more.
Step-by-step explanation:
Account A will pay 5.5% simple interest until the account is paid.
Therefore, after 4 years the principal $5500 will grow up to dollars.
Now, Account B will pay 4.5% simple interest and if the account is left open for longer than 3 years, then at the end of the third year a bonus account will be opened with $250 that also earns 4.5% for the remainder of the time the initial account is open.
Therefore, after 4 years the principal $5500 will grow with a simple interest of 4.5% and the bonus $250 will earn the same rate of simple interest for 1 year.
Hence, the total sum will become dollars.
Therefore, account B is the better choice for earning her (6751.25 - 6710) = $41.25 more. (Answer)
