Question

упрстите:
1)25а⁵в/5а²;
2)0,16ху⁴/2ху;
3)8а‐2в³/2²ав³.​

Answer 1

Объяснение:

$1)25 {a}^{5} b \div 5 {a}^{2} \\ \frac{25 \times {a}^{5} \times b }{5 \times {a}^{2} } \\ 5 \times {a}^{3} \times b \\ 2)0.16x {y}^{4} \div 2 \times xy \\ \frac{ \frac{16}{100} \times x \times {y}^{4} }{2 \times x \times y} \\ \frac{8}{100} \times {y}^{3}$
