Answer 1

Penyelesaian

3! x 5!

( 3 x 2 x 1 ) x ( 5 x 4 x 3 x 2 x 1 )

( 6 x 1 ) x ( 20 x 3 x 2 x 1 )

( 6 x 1 ) x ( 60 x 2 x 1 )

( 6 x 120 )

720

89 × x = 6.408

x = 6.408 ÷ 89

x = 72

K = 12 x Sisi

K = 12 x 12

K = 144 cm

K = 144 ÷ 10 ÷ 10

K = 14,4 ÷ 10

K = 1.44meter

Answer 2

Nomor 1

3! × 5!

= (3 × 2 × 1) × (5 × 4 × 3 × 2 × 1)

= 6 × (20 × 6)

= 6 × 120

= 720

Nomor 2

89 . x = 6.408

x = 6.408 ÷ 89

x = 72

Nomor 3

K = 12 × s

K = 12 × 12

K = 144 cm

K = 1,44 m
