Answer 2

Answer:

It is difficult to read numbers like 12345678900000 or 0.000000002345678. To make it easy to read very large and small numbers, we write them in standard form.

Any number that we can write as a decimal number, between 1.0 and 10.0, multiplied by a power of 10, is said to be in standard form.

1.98 ✕ 10¹³; 0.76 ✕ 10¹³ are examples of numbers in standard form.
