(2-6i) (4-5i) find the product and use answer in a+bi

my dude, this isn't answerable due to the fact there is no question or clear desc of what you want them to do.

0.61 has 2 decimal places, so we put the decimal digits of 0.61, 61 over 1 followed by the number of zeroes equal to the number of decimal places, 

2:     61/1 = 61/100.
