Habisin poin O-o lage_-

penyelesaian :

batas nya adalah 5 dan variabel X diketahui adalah 1 sampai 5 jadi :

= ( 1x + 3 ) + ( 1x + 3 ) + ( 1x + 3 ) + ( 1x + 3 ) + ( 1x + 3 )

= ( 1 (1) + 3 ) + ( 1 (2) + 3 ) + ( 1 (3) + 3 ) + ( 1 (4) + 3 ) + ( 1 (5) + 3 )

= ( 1 + 3 ) + ( 2 + 3 ) + ( 3 + 3 ) + ( 4 + 3 ) + ( 5 + 3 )

= 4 + 5 + 6 + 7 + 8

= 9 + 13 + 8

= 22 + 8

= 30

$sf huge sum_ {x = 1}^{5}(1x + 3) \$

= (1(1) + 3) + (1(2) + 3) + (1(3) + 3) + (1(4) + 3) + (1(5) + 3)

= (1 + 3) + (2 + 3) + (3 + 3) + (4 + 3) + (5 + 3)

= 4 + 5 + 6 + 7 + 8

= 9 + 6 + 7 + 8

= 15 + 7 + 8

= 22 + 8

= 30
