giúp vs nhanh lên nha chỉ còn 1 chút thời gian thoi !

Answer 1

Dễ thôi mà !!!

\(\left(5^7+5^9\right).\left(6^8+6^{10}\right).\left(2^4-4^2\right)\)

= \(\left(5^7+5^9\right).\left(6^8+6^{10}\right).\left(2^4-\left(2^2\right)^2\right)\)

= \(\left(5^7+5^9\right).\left(6^8+6^{10}\right).\left(2^4-2^4\right)\)

= \(\left(5^7+5^9\right).\left(6^8+6^{10}\right).0\)

= 0

Answer 2

(5⁷ + 5⁹)(6⁸ + 6¹⁰)(2⁴ - 4²)

= (5⁷ + 5⁹)(6⁸ + 6¹⁰) . 0

= 0
