Quiz (69/100).
Jawaban:
1.) 6^2 + 3^2 + 2^2 + 5^2 + 9^2
(6×6) + (3×3) + (2×2) + (5×5) + (9×9)
36 + 9 + 4 + 25 + 81
45 + 4 + 25 + 81
49 + 25 + 81
74 + 81
= 155
2.) 9^2 + 10^2 + 2^2 + 5^2 + 9^2
(9×9) + (10×10) + (2×2) + (5×5) + (9×9)
81 + 100 + 4 + 25 + 81
181 + 4 + 25 + 81
185 + 25 + 81
210 + 81
= 291
Penjelasan dengan langkah-langkah:
6^2 + 3^2 + 2^2 + 5^2 + 9^2 =
= (6×6) + (3×3) + (2×2) + (5×5) + (9×9)
= 36 + 9 + 4 + 25 + 81
= 49 + 25 + 81
= 155
9^2 + 10^2 + 2^2 + 5^2 + 9^2 =
= (9×9) + (10×10) + (2×2) + (5×5) + (9×9)
= 81 + 100 + 4 + 25 + 81
= 291
