回答1:

2( 5x - 3 )” - 48 = 0,
( 5x - 3 )” - 24 = 0,
( 5x - 3 )” - ( 2√6 )” = 0,
( 5x - 3 - 2√6 )( 5x - 3 + 2√6 ) = 0,
解方程得,
x1 = ( 3 + 2√6 )/5,
x2 = ( 3 - 2√6 )/5,

回答2:

2( 5x - 3 ) - 48 = 0,
( 5x - 3 ) - 24 = 0,
( 5x - 3 )- ( 2√6 ) = 0,
( 5x - 3 - 2√6 )( 5x - 3 + 2√6 ) = 0,
解方程得,
x1 = ( 3 + 2√6 )/5,
x2 = ( 3 - 2√6 )/5,
