Q.
Ditanya :
1. √9 × √9 × √144 = …?
2. 4! + 3! × 6! ÷ 2! = …?
3. 8^2 × √144 + √169 = …?
penyelesaian :
★ No 1 ★
1. √9 × √9 × √144
= 3² × 3² × 12²
= 3 × 3 × 12
= 9 × 12
= 108 √
★ No 2 ★
2. 4! + 3! × 6! ÷ 2!
4!
= 4 × 3 × 2 × 1
= 12 × 2 × 1
= 24 × 1
= 24
3!
= 3 × 2 × 1
= 6 × 1
= 6
6!
= 6 × 5 × 4 × 3 × 2 × 1
= 30 × 4 × 3 × 2 × 1
= 120 × 3 × 2 × 1
= 360 × 2 × 1
= 720 × 1
= 720
2!
= 2 × 1
= 2
4! + 3! × 6! ÷ 2!
= 24 + 6 × 720 ÷ 2
= 24 + 4.320 ÷ 2
= 24 + 2.160
= 2.184 √
★ No 3 ★
3. 8^2 × √144 + √169
= ( 8 × 8 ) × 12² + 13²
= 64 × 12 + 13
= 768 + 13
= 781 √
Keterangan :
1. √9 × √9 × √144 = 108
2. 4! + 3! × 6! ÷ 2! = 2.184
3. 8^2 × √144 + √169 = 781
semoga membantu
