What is the steps for 13+[9x(3x2)-12]x4

181

Step-by-step explanation:

Assuming that the 'x's' all symbolize multiplication, follow these steps.

First, begin with the innermost set of parenthesis: 3x2

This will give you the answer of six, this will now give you the new equation of:

13+[9x(6)-12]x4

Following the rules of PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction), it is inferable that you must multiply before subtracting the twelve.

Perform this step: 9x6 to get the answer of 54.

13+[54-12]x4

Now, as there are still brackets, perform the bracketed information:

54 - 12 = 42

This now gives you: 13+[42]x4

Yet again, following the rules of PEMDAS, you multiply 42x4 then add the result of that to 13.

42x4 = 168

168 + 13 = 181

Therefore, this expression provides the answer of 181.

Hope this helps!
