There are seven digits: 8,000,000
two
400 x 4 = 1600 Therefore, four digits.
-- Ignore the decimal point; just multiply the two whole numbers. -- After the multiplication is done, put the decimal point back into the product. Put it in the right place so that the product has as many digits after the point as the original decimal had. If there aren't enough digits in the product to do that, add some zeros to the left end of it.
However many digits are after the decimals, that's how many times you move it to the left. For example: 1.38 x 9.24. When you get the product, you would move the decimal 4 places to the left because you have 4 digits after decimals. Hope this helps! (:
There are 15 of them.
When a number is multiplied by itself, its product is called its exponent. When a number is multiplied by itself 30 times, this is the number's 30th exponent, or its 30th power. Two multiplied by two 30 times is 1,073,741,824. It has 10 digits.

5 of them.
from 3 digits (10x10) to 4 digits (99X99)
If you mean, "What is the largest number of digits possible in the product of two 2-digit numbers" then 99 * 99 = 9801, or 4 digits. Anything down to 59 * 17 = 1003 will have 4 digits.
Four
180 times 10 to the power of 4 is 1,800,000 which has five zeros in it
2 digits because 1.88*71 = 133.48
121
