1. вычислите: log5 1/25 + log2 64 2.вычислите: log2 1/4 + log3 27 3.вычислите: log2 5 + log2 8/5 4.вычислите: log3 2 + log3 9/2 максимально ! !

1. log5 1/25 + log2 64 = log5 5^(-2) + log2 2^6 = -2 + 6 = 4
2. log2 1/4 + log3 27 = log2 2^(-2) + log3 3^3 = -2 + 3 = 1
3. log2 5 + log2 8/5 = log2 (5* 8/5) = log2 8 = log2 2^3 = 3
4. log3 2 + log3 9/2 = log3 (2*9/2) = log3 9 = log3 3^2 = 2
