3(2+32(45)21)3(2+4(42)8+3(25)+12)13)+45
rather silly question, and some of it makes no sense
eg look at the first part
......2(45)21
does this end up 2(1)(2) ? or did you forget an operator before the last 2?
there is a similar discrepancy near the end of the mess.
3(2+32(45)21)3(2+4(42)8+3(25)+12)13)+45

First, get rid of the parentheses within the parentheses by combining those terms. I will assume a plus sign in front of the third 2 and the last 1.
3(2+32(45)21)3(2+4(42)8+3(25)+12)13)+45
3(2+3+1+21)3(2+889+12+13)+45
Next combine terms within the parentheses, multiply and then add the products.
I hope this helps. Thanks for asking.
