Solution Steps

00:00 Solve the following expression
00:03 Solve the parentheses first
00:09 Maintain the proper order of operations within the parentheses
00:18 Given that there are only multiplication/division exercises within the parentheses, solve from left to right
00:26 Continue to solve the expression according to the proper order of operations
00:33 Multiplication and division always precede addition and subtraction
00:38 Continue to solve the expression according to the proper order of operations
00:48 This is the solution

Step-by-Step Solution

Simplify this expression whilst following the order of operations . The order of operations states that exponents precede multiplication and division, which in turn precede addition and subtraction, and that parentheses precede all of the above:

Therefore, we'll start by simplifying the expressions inside of the parentheses. Note that in this expression there are parentheses within parentheses. Begin by simplifying the expression in the innermost parentheses and perform the addition operation within them:

9664:((5+13):94)+48=9664:(18:94)+48 96-64:\big((5+13):9\cdot4\big)+48= \\ 96-64:\big(18:9\cdot4\big)+48

Proceed to the division and multiplication operations that remain inside of the parentheses.

Follow the natural order of operations from left to right, given that there are no additional parentheses in this expression (within the parentheses) as well as no defined order as mentioned above. Therefore we'll first perform the division operation and then the multiplication operation:

9664:(18:94)+48=9664:(24)+48=9664:8+48 96-64:\big(18:9\cdot4\big)+48=\\ 96-64:\big(2\cdot4\big)+48=\\ 96-64:8+48

Remember that multiplication and division precede addition and subtraction. Therefore we'll first perform the division operation and only in the next step the subtraction and addition operations:

9664:8+48=968+48=136 96-64:8+48 =\\ 96-8+48 =\\ 136

Let's summarize the steps of simplifying the expression:

9664:((5+13):94)+48=9664:(18:94)+48=9664:8+48=136 96-64:\big((5+13):9\cdot4\big)+48= \\ 96-64:\big(18:9\cdot4\big)+48=\\ 96-64:8+48 = \\ 136

Therefore, the correct answer is answer B.
