Question

сократите дробь 45а^3 b^3 / 54 a^4 b^3​

Answer 1

Ответ:

$\frac{ 45a ^ { 3 } b ^ { 3 } }{ 54a ^ { 4 } b ^ { 3 } } = \frac{45^{1}a^{3}b^{3}}{54^{1}a^{4}b^{3}} = \frac{45^{1}}{54^{1}}a^{3-4}b^{3-3} = \frac{45^{1}}{54^{1}}\times \left(\frac{1}{a}\right)b^{3-3} = \frac{45^{1}}{54^{1}}\times \left(\frac{1}{a}\right)b^{0} = \frac{45^{1}}{54^{1}}\times \left(\frac{1}{a}\right) = \frac{5}{6}\times \left(\frac{1}{a}\right) = \frac{5}{6a}$
