Answer 2

Answer:Your answer will be 1.21 * 10^8.

Step-by-step explanation:

To write it in the form of standard form, we first have to write it numerically;

Hence,          one hundred twenty one million dollars  = 121,000,000;

Now, write it in the form of rational number;

                            = 121,000,000 / 1

Now, divide its numerator by 100,000,000.

Hence,                = (121,000,000 / 100,000,000) / (1 / 100,000,000)

                           = (121,000,000 / 100,000,000) * 100,000,000 / 1;

                          = 1.21 * 100,000,000 / 1;

                          = 1.21 * 10^8 .

So, this was the standard form of one hundred twenty one million dollar.

That's all.
