Answer:

The boy band sold  1.89 ×10^6 copies

Step-by-step explanation:

To get the number of copies we must add 5.9×10^5 copies with 1.3×10^6  copies.  We can´t add them  like that.

To make the addition we have to adjust the power of 10,  so they have the same index

In this case we can change  5.9×10^5 to 0.59×10^6 ( we move the comma to the left , and we add 1 power to the scientific quotation.

So, 0.59×10^6

<u />

<u>+    1.3×10^6  </u>

     1.89 ×10^6

How do I round 47,283 to the nearest 100,000
rosijanka [135]

The answer is zero.

Explanation:

The 4 is in the ten-thousands place.

Write the number 47,283 with an additional zero in the 100,000 place.

047,283

To round to the nearest 100,000, all digits to the right of the 100,000 place become zero. That means that the digits 47283 all become zero. Since 4 is less than 5, the digit to its left is not raised by 1, so the 100,000 place digit remains zero, and you end up with 000,000, which is simply 0.
