Quizplus · Accepted Answer

First, calculate the expression inside the parentheses: $1.7 - 2.1 = -0.4$. Then, square this result: $(-0.4)^2 = 0.16$. Next, perform the division and multiplication in order: $1.1 \div 2.5 = 0.44$, and then $0.44 \cdot 0.16 = 0.0704$. Finally, subtract this result from 2.7: $2.7 - 0.0704 = 2.6296$.
