Answer:
50000000000
Step-by-step explanation:
For (5×10^– 2): 10 to the negative second power equals -100. 5 x -100 = -500.
For (1×10^– 8): 10 to the negative eighth power equals -100000000. Multiplied by one is obviously the same exact number. So -500 x -100000000 = 5000000000. Remember that negative numbers multiplied by negative numbers will always equal positive numbers. And positive numbers multiplied by negative numbers will always equal negative numbers.
