Answer:
A. She had $170.47 more in debits than in credits.
Step-by-step explanation:
In a bank account, when money is deposited, the bank credits the bank accounts while a withdrawal is debited to the account hence, if the monthly bank statement for Sierra's checking account was $402.22, and the ending balance was $231.75, the change in the account is
= $402.22 - $231.75
= $170.47
Since there was a drop in the balance comparing the beginning and ending balances, it means there were more withdrawals than deposits (in amount).
We assume that we need to simplify the expression in two different ways.
Answer:
One way: Raise both, the numerator and denominator, to the third power, and then simplify the expression.
Second way: Simplify the terms inside parentheses, and then raise the result to the third power.
The result of both ways is the same: 
Step-by-step explanation:
<em>One way</em>
Raise both, the numerator and denominator, to the third power, and then simplify the expression:





This is the first simplification.
<em>Second way</em>
Simplify the terms inside parentheses, and then raise the result to the third power.
