Question

`2^ 3. x + 5 ^ 2. x =2(5 ^ 2 + 2 ^3 ) -33`

Answer 1

`2^ 3. x + 5 ^ 2. x =2(5 ^ 2 + 2 ^3 ) -33`

`=> 8x + 25x = 2 ( 25 + 8 ) - 33`

`=>x(25 + 8) = 2 . 33 - 33`

`=> x . 33 = (2-1).33`

`=> x . 33 = 33`

`=> x = 33 : 33`

`=> x =1`

Answer 2

Lời giải:

$2^3x+5^2x=2(5^2+2^3)-33$

$8x+25x=2(25+8)-33$

$33x=33$

$x=33:33$

$x=1$
