What is one million times one thousand in scientific notation

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

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.
