(8т 4ц 24кг + 10кг 506г) * 64

First, convert all weights to grams:
8т = 8,000кг = 8,000,000г
4ц = 4кг = 4,000г
24кг = 24,000г
10кг = 10,000г
506г = 506г

Add all the weights together:
8,000,000г + 4,000г + 24,000г + 10,000г + 506г = 8,038,506г

Now, multiply by 64:
8,038,506г * 64 = 514,144,384г

Therefore, (8т 4ц 24кг + 10кг 506г) * 64 = 514,144,384г
