Tens of quintillions.
225 = (15)2 2*2*5=20 3 digits in 225
When using significant digits, the product has only the number of significant digits as the lowest number in the factors. "20" has two significant digits and "310" has three. Therefore, the product has to have two significant digits. 310 × 20 = 6200 6200 already has two significant digits.

To write the numbers from 1 to 20, we need to count the digits used for each range. The numbers 1 to 9 use 1 digit each, totaling 9 digits. The numbers 10 to 20 use 2 digits each, totaling 22 digits (11 numbers). Therefore, the total number of digits required to write all the numbers from 1 to 20 is 9 + 22 = 31 digits.
...Any number that has 20 digits! For example, 10,000,000,000,000,000,000 (10 quintillion)

Digits is how many numbers you have in a number. If you have the number 4 it has one digit if you have the number 20 it has two digits and if you have the number 558 it has three digits. So basically in the number 1085 it has 4 digits because there is 4 numbers in it, the numbers are 1,0,8 and 5. Hoped you understand.
To find the mean of the digits in the number 2468, first, add the digits together: 2 + 4 + 6 + 8 = 20. Then, divide the sum by the number of digits, which is 4: 20 ÷ 4 = 5. Therefore, the mean of the digits in 2468 is 5.
A quintillion is a number with 18 zeros (19 digits). A 20-digit number would be 10's of a quintillion (20 digits since we add one more digit to the left).
The number 20 has two significant figures. In scientific notation, it would be written as 2.0 x 10^1, indicating that both digits are significant. Significant figures are the digits in a number that carry meaning contributing to its precision.
It depends where you are calling from:If you are making the call to a land-line from within Giza or Cairo (i.e. a local call), it's 8 digits; e.g. 12345678If you're calling a land-line from outside Giza or Cairo (e.g. Alexandria), you prefix the number with 02; e.g. 02-12345678 (10 digits)If you're calling a land-line from outside Egypt, you prefix the number with +202; e.g. +20-2-12345678If you're calling a cell number from outside Egypt, you prefix the number with +20; e.g. +20-10-123-4567
