1000000•1000000000000000=?

The calculation \(1,000,000 \times 1,000,000,000,000,000\) can be simplified as follows:

\[ 1,000,000 = 10^6 \] \[ 1,000,000,000,000,000 = 10^{15} \]

Now, multiplying these two values:

\[ 10^6 \times 10^{15} = 10^{(6+15)} = 10^{21} \]

So the result is:

\[ 1,000,000 \times 1,000,000,000,000,000 = 10^{21} = 1,000,000,000,000,000,000,000 \]

In standard form, the answer is \(1,000,000,000,000,000,000,000\).
