q. eycoak

l = √25 + √20 + √8
o = √100 + √50
a = √125
d = 2√5

Tentukan :
l × o × a × d
_____________
ada yg suka sama ini?

Penjelasan dengan langkah-langkah:

l = √25 + √20 + √8

= 5 + 2√5 + 2√2

o = √100 + √50

= 10 + 5√2

a = √125

= 5√5

d = 2√5

penyelesaian :

a × d = 5√5 × 2√5 = 50

o × a × d = 50(10 + 5√2) = 500 + 250√2

l × o × a × d = (5 + 2√5 + 2√2)(500 + 250√2)

= 5(500 + 250√2) + 2√5(500 + 250√2) + 2√2(500 + 250√2)

= 1.250(2 + √2) + 500(2 + √2)√5 + 1000(1 + √2)

I × O × A × D
( √25 + √20 + √8 ) × ( √100 + √50 ) × ( √125 ) × 2√5
( 5 + √4×5 + √4×2 ) × ( 10 + √25×2 ) × ( √25×5 ) × 2√5
( 5 + 2√5 + 2√2 ) × ( 10 + 5√2 ) × 5√5 × 2√5
( 5 × 10 ) × ( 2√5 × 5√5 × 2√5 ) × ( 2√2 × 5√2 )
50 × ( ( 2 × 5 ) ( √5 × √5 ) × 2√5 ) × ( ( 2 × 2 ) ( √2 × √2 )
50 × ( ( 10 × √25 ) × 2√5 ) × ( 4 √4 )
50 × ( ( 10 × 5 ) × 2√5 ) × ( 4 × 2 )
50 × ( ( 50 ) × 2√5 ) × 8
50 × ( 100√5 ) × 8
( 50 × 100 × 8 )√5
( 5.000 × 8 )√5
40.000√5
