how do I simplify the following expressions and show my work? 6+5[(12 div. by2)+5]. (4div.by2)+8(53)to the second power. 872Div.by9x4to the second power + 11.

Start by changing "12 div. by 2" to 6 and
"8(53)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.
