2³ + √100 × 30

= ( 2.2.2 ) + √10² × 30

= 8 + 10 × 30

= 8 + 300

= 308

5! + √2.500 × 5

= ( 5.4.3.2.1 ) + √50² × 5

= 120 + 50 × 5

= 120 + 250

= 370

= 2³ + √100 × 30

= ( 2 × 2 ) × 2 + √100 × 30

= ( 4 × 2 ) + √100 × 30

= 8 + √100 × 30

= 8 + ( 10 × 30 )

= 8 + 300

= 308 ( terbukti )

= 5! + √2500 × 5

= ( 5 × 4 ) × 3 × 2 × 1 ) + √2500 × 5

= ( 20 × 3 ) × 2 × 1 ) + √2500 × 5

= ( 60 × 2 ) × 1 ) + √2500 × 5

= ( 120 × 1 ) + √2500 × 5

= 120 + √2500 × 5

= √2500 × 5

= 50 × 5

= 120 + 250

= 370 ( terbukti )
