pke jalan nya juga nihh soob :s . tlng di bntu yaah :) ?

Answer 1

1.(akar 8 x akar 3) akar 2= akar 24 x akar 2
= akar 48 = akar 16 x3
= 4 akar 3
2.(akar 3 + akar 5) (akar 3 - akar 5)
=akar 9 - akar 15 + akar 15 - akar 25
= akar 9 - akar 25
= akar -16
= -4
3.akar 12 x akar 3 = akar 36
= 6
4. 2 akar 48 x akar 6 = 2 akar 16 .3 x akar 4.2
= 2.4 akar 3 x 2 akar 2
= 8 akar 6 x 2 akar 2
= 16 akar 12
= 16 akar 4.3
= 64 akar 3
