j: \(\left(5^7+7^5\right)\left(6^8+8^6\right)\left(2^4-4^2\right)\)

\(=\left(5^7+7^5\right)\left(6^8+8^6\right)\left(16-16\right)\)

\(=0\cdot\left(5^7+7^5\right)\left(6^8+8^6\right)\)

=0

k: \(\left(7^{50}+7^{29}\right)\left(5^{14}+5^{26}\right)\left(3^{35}\cdot3-9^{18}\right)\)

\(=\left(7^{50}+7^{29}\right)\cdot\left(5^{14}+5^{26}\right)\left(3^{36}-3^{36}\right)\)

\(=\left(7^{50}+7^{29}\right)\left(5^{14}+5^{26}\right)\cdot0=0\)

                             Giải:

Thời gian ô tô xuất phát trước xe khách là: 10 giờ - 7 giờ = 3 giờ

Khi xe khách xuất phát ô tô cách xe khách là: 30 x 3 = 90 (km/h)

Hai xe gặp nhau sau: 90 : (60 - 30) = 3 (giờ)

Lúc gặp nhau cách A là: 60 x 3 = 180 (km)

Lúc gặp nhau cách B là:  230 - 180 = 50 (km)

Kết luận: Hai xe gặp nhau sau 3 giờ 

              Vị trí gặp nhau cách A là 180 km, cách B là 50 km
