Answer:
35/8 if its simple multiple then
Step-by-step explanation:
7/4*5/2

If you're multiplying these terms with imaginary parts, do it just like you would any binomial multiplication. (4x+3i)(7x+4i). FOIL-ing that out we get, before simplification,
. There are 2 things to simplify here: Combining like terms and then dealing with the squared i.
is equal to -1, so 12(-1) = -12. Then we will combine the ix terms and in the end we will have
