In the future, would you please post just one or two problems at a time. Be fair to others who also want help.
#5: <span>(-4)^8/(-4)^4 can be expressed more clearly as (-4)^8
---------
(-4^4)
and this can be reduced to (-4)^4 by subtracting the exponent 4 from the
exponent 8.
furthermore, because of the even exponent, (-4)^4 can be written as 4^4.
Note that 4^4 = (4^2)^2 = 16^2 = 256 (answer)</span>
(-7+2i)(3-5i)
=(2i-7)(-5i+3)
=-10i^2+41i-21.
Hope it help!
