Question

punctul B va rog!!!!!!!!

Answer 1

Răspuns:

$= \frac{40}{21}$

Explicație pas cu pas:

$\frac{2^{6}*3^{4} * 5^{2} *7}{2^{3}*5*3^{5} * 7^{2} } =$

$= \frac{2^{6} }{2^{3} } *\frac{3^{4} }{3^{5} } *\frac{5^{2} }{5} * \frac{7}{7^{2} }$

$= 2^{3} * \frac{1}{3} *5 *\frac{1}{7} = \frac{2^{3} *5}{3*7} = \frac{8*5}{21} = \frac{40}{21}$

Answer 2

Răspuns:

a=2⁶×3⁴×5²×7

b=2³×5×3⁵×7²

a/b=2⁶:2³×3⁴:3⁵×5²:5×7:7²

a/b=2⁶⁻³×3⁴⁻⁵×5²⁻¹×7⁻¹

a/b=2³×1/3×5×1/7

a/b=40/21
