$\frac{36}{60} = \frac{3}{5}$

Simplifici prin 12.

$\frac{18}{12} = \frac{3}{2}$

Simplifici prin 6.

$\frac{7a}{5a} = \frac{7}{5}$

Simplifici prin a.

$\frac{2(x + 1)}{4(x + 1)} = \frac{2}{4} = \frac{1}{2}$

Simplifici prin x+1. Simplifici prin 2.

$\frac{2^{4} \times {5}^{3} \times {7}^{3} }{ {2}^{3} \times {5}^{4} \times 7 } = \frac{2 \times {7}^{2} }{5} = \frac{2 \times 49}{5} = \frac{98}{5}$

Simplifici expresiile: 2^4 cu 2^3, 5^3 cu 5^4 si 7^3 cu 7.

b)

$\frac{3^{2} }{3 \times 5} = \frac{9}{15} = \frac{3}{5}$

Simplifici prin 3.

$\frac{ {2}^{2} \times 3 }{2^{5} \times {3}^{2} } = \frac{1}{ {2}^{3} \times 3} = \frac{1}{8 \times 3} = \frac{1}{24}$

Simplifici expresiile: 2^2 cu 2^5 si 3 cu 3^2.

$\frac{2 \times 3 \times {5}^{3} }{2 \times {3}^{2} \times 5 } = \frac{ {5}^{2} }{3} = \frac{25}{3}$

Simplifici prin 2. Simplifici expresiile: 3 cu 3^2 si 5^3 cu 5.

$\frac{ {5}^{2} \times {7}^{3} \times {11}^{4} }{3^{5} \times {7}^{3} \times {11}^{2} } = \frac{5^{2} \times {11}^{2} }{ {3}^{5} } = \frac{55^{2} }{243} = \frac{3025}{243}$

Simplifici prin 7^3. Simplifici expresia: 11^4 cu 11^2.

$\frac{144}{ {7}^{2} \times 12 } = \frac{12}{ {7}^{2} } = \frac{12}{49}$

Simplifici prin 12.

$\frac{ {13}^{2} \times {17}^{4} \times 19 }{ {13}^{2} \times {7}^{3} \times 23 } = \frac{19 \times {17}^{4} }{23 \times {7}^{3} } = \frac{19 \times 83521}{23 \times 343} = \frac{1586899}{7889}$

Simplifici prin 13^2.

$\frac{ {5}^{11} \div {5}^{6} \times 3 \div 3}{ {5}^{3} \times {5}^{2} \times {3}^{2} \times 7 } = \frac{ {5}^{11} \div {5}^{6} \times 1 }{ {5}^{3} \times {5}^{2} \times 9 \times 7 } = \frac{ {5}^{5} }{ {5}^{3} \times {5}^{2} \times 9 \times 7 } = \frac{ {5}^{2} }{5^{2} \times 9 \times 7} = \frac{1}{9 \times 7} = \frac{1}{63}$

Simplifici expresia 5^5 cu 5^3. Simplifici prin 5^2.
