15.5*\lbrack(2*2.4)+3.2\rbrack-2^4

Let's use PEMDAS in order to determine the order of the operations:

P: Parentheses

E: Exponents

M: Multiplication

D: Division

A: Addition

S: Subtraction

So:


\begin{gathered} 15.5*\lbrack4.8+3.2\rbrack-2^4 \\ 15.5*8-2^4 \\ 15.5*8-16 \\ 124-16 \\ 108 \end{gathered}

Answer:

108
