Answer:
4*2*5/2=20
Step-by-step explanation:
To determine this easily, figure out what two numbers will make a product ending with "2", (4 & 3, 8 & 9)
Since the square root of 625 is 25, it is obviously less than 25.
I used 18 and 19, and they are the correct answer.
((1+4i)/i) +(1+i)/(2+5i)
(((1+4i)*(2+5i)) +((1+i)*<span>i))/(i*(2+5i))
</span>((2 + 8i + 5i +20i²) + (1i + i²) )/ (2i + 5i<span>²)
((2 + 13i -20) + (1i -1))/(2i - 5) where </span>i<span>² = -1</span><span>
((14i - 19) +0)/2i - 5
(14i -19)/(2i - 5) </span>
