Question

prove that 0.75×0.75 ×0.75×0.25×0.25×0.25\0.75×0.75-0.75×0.25+0.25×0.25=1

Answer 1

your answer is
$0.75 \times 0.75 \times 0.75 \times 0.25 \times 0.25 \times 0.25 \div 0.75 \times 0.75 - 0.75 \times 0.25 + 0.25 \times0.25 \\ \frac{0.75 \times 0.75 \times 0.25 \times 0.75 \times 0.25 \times 0.25}{0.25(3 \times 3 - 3 \times 1 + 1 \times 1)} \\ 0.00376674107$
