Question

Помогите решить эти логорифмы​

Answer 1

Ответ:

${a}^{ loga(b) } = b$

$1)5 \times 2 = 10$

$2)10 \times 7 = 70$

$3)9 \times 3 = 27$

$4)13 \times 3 = 39$

$5)11 \times 9 = 99$

$6)2 \times {10}^{ log10(4) } = 2 \times 4 = 8$

$7)2 \times 4 = 8$

$8) {3}^{2 \times log3(7) } = {3}^{ log3(49) } = 49$

$9) {7}^{2 \times log7(12) } = {7}^{ log7(144) } = 144$

$10) log6(90 \div 2.5) = log6(36) = 2$

$11) log6(54 \div 1.5) = log6(36) = 2$

$12) log12(252 \div 1.75) = log12(144) = 2$
