Q.63^2 + 62^2 – 53^2 = 6! × 2! + 5! =note : guabuttt
63² + 62² – 53²
= (63×63) + (62×62) – (53×53)
= 3.969 + 3.844 – 2.809
= 7.813 – 2.809
= 5.004✔
6! × 2! + 5!
= (6×5×4×3×2×1) × (2×1) + (5×4×3×2×1)
= 720 × 2 + 120
= 1.440 + 120
= 1.560✔
Jawaban:
62^2 + 62^2 – 53^2 = 1.035
6! × 2! + 5! = 1.560
Penjelasan:
62^2 = 62 × 62 = 3.844
63^2 = 63 × 63 = 3.969
53^2 = 53 × 53 = 2.809
6! = 6 × 5 × 4 × 3 × 2 × 1 = 720
2! = 2 × 1 = 2
5! = 5 × 4 × 3 × 2 × 1 = 120
Penyelesaian:
3.969 + 3.844 – 2.809 = 5004
720 × 2 + 120 = 1. 560
