Question

thim x

(7x-11)^3=2^5.5^2+200

 

Answer 1

(7x-11)³=2⁵.5²+200

(7x-11)³=1000

(7x-11)³=10³

7x-11=10

7x=10+11

7x=21

x=21:7

x=3

Answer 2

( 7x - 11 ) ³ = 32 . 25 + 200

( 7x - 11 ) ³ = 800 + 200

( 7x - 11 ) ³ = 1000

( 7x - 11 ) ³ = 10³

7x - 11 = 10

7x = 10 + 11

7x = 21

x = 21 : 7

x = 3
