Answer 1

$= (5 \times {1}^{6}) \times ( - 10 \times 1 \times( \frac{ {1}^{2} }{ {2}^{2} } ) \times ( - 2.1 \times 1 \times \frac{ {1}^{3} }{ {2}^{3} } ) \\ = 5 \times ( - 10 \times \frac{1}{4} ) \times ( - 2.1 \times \frac{1}{8} ) \\ = 5 \times \frac{ - 10}{4} \times \frac{ - 2.1}{8} \\ = \frac{ - 50}{4} \times \frac{ - 2.1}{8} \\ = \frac{105}{32} \\ = 3.28125 \\ mark \: as \: brainliest \: ....... \: \:$
