Answer: B and D
Step-by-step explanation:
First, solve the terms inside of the parenthesis. As a general rule, whenever you multiply two terms that have the same base, you can add their exponents.
Applying this rule, the base in the problem is 6, and the exponents are 3 and -4. The sum of 3 and -4 leaves -1. Therefore, this is one of our solutions:

When you have an exponential term raised to another exponent, you can simply multiply the exponents. In the previous solution given above, multiply -1 and -3 to get 3. Therefore our second solution is:

5
you use the formula a^2+b^2=c^2
a=3, b=4
3*3=9 and 4*4=16
16+9=25
square root of 25 is 5.
5 is the answer
<h3>Given</h3>
new balance = previous balance + finance charge + purchases - payments
previous balance = $34.80
finance charge = $0.75
purchases = $83.21
payments = $5.50
<h3>Find</h3>
new balance
<h3>Solution</h3>
Fill in the given information and do the arithmetic.
... new balance = previous balance + finance charge + purchases - payments
... new balance = $34.80 + 0.75 + 83.21 - 5.50
... new balance = $113.26 . . . . matches the 2nd choice
I believe its 27.75. I wouldn't take my word for it though.
