5. Evaluate (11.2)^2-(0.375div 3) and express your answer: (1 mark)

To evaluate the expression $(11.2)^{2}-(0.375\div 3)$, we need to follow the order of operations, which is often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).<br /><br />First, let's calculate the exponent:<br />$(11.2)^{2} = 11.2 \times 11.2 = 125.44$<br /><br />Next, let's perform the division:<br />$0.375\div 3 = 0.125$<br /><br />Finally, let's subtract the second result from the first result:<br />$125.44 - 0.125 = 125.315$<br /><br />Therefore, answer is 125.315.
