Question

√75 + √8-( √32 + √48 )

Answer 1

√75 + √8-( √32 + √48 )
= 5√3 + 2√2 - ( 4√2 + 4√3 )
= 5√3 + 2√2 - 4√2 - 4√3
=(5√3-4√3) + (2√2-4√2)
=√3-2√2

Answer 2

Akar 75 = 5 akar 3
akar 8 = 2 akar 2
akar 32 = 4 akar 2
akar 48 = 4 akar 3

5 akar 3 + 2 akar 2 - (4 akar 2 + 4 akar 3)
=5 akar 3 + 2 akar 2 - 4 akar 2 - 4 akar 3
=5 akar 3 - 4 akar 3 - 4 akar 2 + 2 akar 2
= akar 3 - 2 akar 2
