Найдите х: log3 x = - 2; log36 x =; log3 x = 3; log64 4 = x; log3 = x; log2 16 = x; logx 16 = 2; logx = - 3; logx 5 =

Найдем х.

1) log3 x = - 2;

x = 3^ (-2);

x = 1/3^2;

x = 1/9;

2) log3 x = 6;

x = 3^6;

x = 9 * 9 * 9;

x = 81 * 9;

x = 729;

3) log3 x = 3;

x = 3^3;

x = 27;

4) log64 4 = x;

64^x = 4;

4^ (4 * x) = 4;

4 * x = 1;

x = 1/4;

5) log3 1 = x;

3^x = 1;

3^x = 3^0;

x = 0;

6) log2 16 = x;

2^x = 16;

2^x = 2^4;

x = 4;

7) logx 16 = 2;

x^2 = 16;

x^2 = 4^2;

x = 4;

8) logx = - 3 * logx 5;
