12^2+2 [(13+3)] / 2^2]
-4(3)+5[7-6(-4)^2]
-5(3)+3[9-6(-3)^2]
please show me how to do these
First, there are no equations, just expressions. If you want to simplify them, just work your way out from the inside parens. In the absence of parens, do powers, then mult/div then add/sub
I'll do the first one:
12^2+2 [(13+3)] / 2^2] -- missing "]" or extra "]" inside. I'll assume extra ] inside.
12^2 + 2[16 / 2^2]
12^2 + 2(16/4)
144 + 2*4
144 + 8
152
