(log3(x-2)- 1)^2+(x-5)^2=0

(log3(x-2)-log3(3))^2+(x-5)^2=0

(x-5)^2+(x-5)^2=0

x^2-10x+25=0

d=100-100=0

x=10/2

4х⁴ * (-2х²)³ = 4х⁴ * (-8х⁶) = -32х¹⁰

с=17

а-b=7

(a-b)^2=49

a^2-2ab+b^2=49

a^2+b^2-2ab=49

a^2+b^2=c^2

a^2+b^2=17^2

a^2+b^2=289

289-2ab=49

2ab=240

ab=120

a=7+b

b(7+b)=120

b^2+7b-120=0

d=529

b=(-7+23)/2

b=8

8a=120

a=15

ответ: 8; 15
