The Attempt at a Solution

I solved through the above equation and got the answer to be 80 and I was wondering if this is correct. When I plug it into wolframalpha, I get 80 as well (as seen here), but I just want to be sure before moving forward.

Any help would be greatly appreciated!

That is not an equation, it is an expressdion! If you are simply asking for its value,

2 log_4(16)= 2(2)= 4 sqrt(4)= 2 3*5^2= 75

2- 75= -73. 3|-73|= 219. 219+ 1= 220. 220*(4/11)= 20*4= 80 so, yes, you are correct.
