(2akar3 + 5akar6)(3akar3 - 4akar6)

langsung aja yy

(2√3 + 5√6)(3√3 - 4√6)

18 - 8√18 + 15√18 - 120

7√18 - 102

7√9×2 - 102

21√2 - 102

semoga berguna +_+

( 2√3 + 5√6 ) × ( 3√3 - 4√6 )

( √4×3 + √25×6 ) × ( √9×3 - √16×6 )
=> ( √12 + √150 ) × ( √27 - √96 )
=> √162 × ( - √69 )
=> ( - √ 11178 )

maaf kalo salah:)
