Question

4. Evaluate the expression15.5 x [(2 x 2.4) + 3.2] - 2^4=

Answer 1

$15.5\times\lbrack(2\times2.4)+3.2\rbrack-2^4$

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:

$\begin{gathered} 15.5\times\lbrack4.8+3.2\rbrack-2^4 \\ 15.5\times8-2^4 \\ 15.5\times8-16 \\ 124-16 \\ 108 \end{gathered}$

Answer:

108
