How do I solve 12-[(3²x4)-30]
start with the first parenthesis wich is 3 two and 4 the exponent of the 3 means 3 three time so it would be 9 x 3 and that is 27 the move to the next parenthesis which is -30 so 27 minus 30 is 3 so three is your anwser
First you do (3^2x4) which equals =36Secondly you do [36-30] which equals = 6Then you take out the brackets 12-6 which equals =6Here is the whole thing: =12-[(9x4)-30]=12-[36-30]=12-6=-6
