Question

верно ли равенство
3) а¹⁷ × а⁴⁷ × а⁵⁶/а⁸¹ × а³⁹ = а⁸⁰ × а⁵ × а³⁷/ а⁵⁹ × а⁶³
4) а³¹ × а¹⁸ × а²⁷ × а¹⁹/а²² × а⁵⁴ × а¹⁶ = а³⁹ × а²³/ а⁵⁹
пожалуйста помогите, даю 25 баллов!!​

Answer 1

$3. \frac{a {}^{17} \times a {}^{47} \times a {}^{56} }{a {}^{81} \times a {}^{39} } = \frac{a {}^{80} \times a {}^{5} \times a {}^{37} }{a {}^{59} \times a {}^{63} }$

$\frac{a {}^{17} \times a {}^{47} \times a {}^{56} }{a {}^{81} \times a {}^{39} } = \frac{a {}^{80} \times a {}^{5} \times a {}^{37} }{a {}^{59} \times a {}^{63} },a≠ 0$

$\frac{a {}^{120} }{a {}^{120} } = \frac{a {}^{122} }{a {}^{122} }$

$1 = 1$
