6 и -3....................
A^loga x = x
1. 7*1/5^2=7/25
2. log 1/9 1/16 = -2 * (-1/2) log 3 4 = log 3 4 //// =4
3. 1/36 = 6^(-2) ////// = 6^(-2log6 3) = 1/9
4. 1/64 = 4^(-3) //// = 4^(-3log4 7) = 7^-3 = 1/343
5. это 2.
1. 5×(-3)^2=5×9=45
2. (-5×3)^2=(-15)^2=225
3. -5×(-3)^3= -5×(-27)=135
4. -(5×3)^2= -15^2= -225
5. 4^2+3^2=16+9=25
6. (-2)^3+(-1)^2= -8+1= -7
7.(-7)^3= -343
Ответ: молодец
В итоге получится (x;y) ,т.е. (-1;1)
