The value of this exspression is 360. According to PEMDAS you do parenthesis first which is 25+5. This equals 30. Now all you have to do is 12 times 30 which is 360 your final answer. Hope this helps.
If you're looking for the answer to the problem (which I assume you are), you would do the equation inside the parentheses first, which would be 30, then you would multiply 12 X 30, which is 360. Hope that helped!
