To write 4.4.4 in exponential form, we need to understand that the decimal point separates the whole number part from the fractional part. In this case, 4.4.4 can be written as 4 + 4/10 + 4/100. To convert this into exponential form, we can write it as 4 + 4/10 + 4/100 = 4 + 4 * 10^-1 + 4 * 10^-2, which simplifies to 4 + 4 * 1/10 + 4 * 1/100 = 4 + 4/10 + 4/100 = 4.4.4.
