how do I simplify the following expressions and show my work? 6+5[(12 div. by2)+5].      (4div.by2)+8(5-3)to the second power.      -8-72Div.by9x4to the second power + 11.

drwls · Answer

Start by changing "12 div. by 2" to 6 and
"8(5-3)to the second power" to 8*(2^2) = 32.

72Div.by9 x 4 to the second power =
8 x (4^2) = 8 x 16 = 128

You should be able to take it from there. Learn to use symbols instead of words when writing math expressions.
