Answer: 1.0x10^9
Step-by-step explanation:
first, one million is:
1,000,000
you can count that we have six zeros, so in scientific notation this is:
1.0x10^6
one thousand is 1,000
we have 3 zeros, so in scientific notation this is:
1.0x10^3
Then, the product of these numbers is:
1.0x10^3*1.0x10^6 = (1.0*1.0)x10^(3 + 6) = 1.0x10^9
