3 times 10 to the first power = 30
10 to the first power is 10. 6.7 x 10 = 67
80.003
53
It is 49320.
658 = (6 x 100) + (5 x 10) + (8 x 1)
67
The first is ten thousand times as large.
I assume you mean 10x10^10 (said as 10 time 10 TO the power of 10) the order of operations means the 10^10 is calculated first which is 10,000,000,000 10 x this = 100,000,000,000
10 to the 4 power times 10 to the 3 power is 10,000,000 (10 million).
It is 6.58, as in the question. But you could write it as 6.58*10^0.
1.004 X 10-1 is equal to 0.1004.
