Factors of 189: 1, 3, 9, 21, 63, 189,
To multiply two digit decimal numbers, multiply the numbers as you would without the decimals. To put the decimal in the answer, count the number of decimal places in the two numbers and put the decimal in the answer that many places to the left. For example: 5.12 x 6.35 = 32.5120. If the numbers were 51.2 x 63.5, the answer would be 3251.20.
There are no two real numbers that do. Using complex numbers, these two do: (-3/2 + i√151/2) & (-3/2 - i√151/2) Two numbers that add to -3 and multiply to -40 are -8 & 5 Two numbers that add to 3 and multiply to -40 are 8 & -5 Two complex numbers that add to 3 and multiply to 40 are (3/2 + i√151/2) & (3/2 - i√151/2)

To find two numbers that multiply to give 378, you can consider its factors. One pair of numbers that works is 14 and 27, since 14 × 27 = 378. Another pair is 2 and 189, as 2 × 189 also equals 378.
You should multiply the numbers, but add the exponents. For example: 92 x 27 = 189
