4.0 x 10-2 * 8.1 x 102 = 32.4
2 significant digits, so the answer is 32.
to 1 significant digit: 8000 2 significant digits: 7700 3 significant digits: 7660 4 significant digits: 7656. 5 significant digits: 7656.0 6 significant digits: 7656.00 and so on and so forth for forever..........

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.

The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
Four significant digits in 50.00.
When multiplying, the product is going to have the same number of significant digits as the least amount in the factors. So 8.08 has three significant digits and 5.232 has four significant digits. Remember that any zeros in-between significant digits is always significant. Because the least amount of sig digs in the factors is three (from 8.08), the product is going to have three sig digs.Multiplying out normally: 8.08 × 5.232 = 42.27456Rounded to three places: 42.3
