Question

(7x-11)^3=2^5*5^2+200

Answer 1

(7x - 11 )^3 = 32*25+200

(7x - 11 ) ^3 = 1000 

(7x-11)^3 = 10^3 

=> 7x - 11 = 10 => 7x = 11 + 10 = 21 => x = 21 : 7 => x = 3 

Answer 2

bạn ơi là 2^5va5^2 bạn 

Answer 3

(7x-11)^3=2^5*5^2+200

(7x-11)^3 = 32 * 25 + 200 

(7x-11)^3 = 800 + 200 

(7x-11)^3 = 1000
