Answer:

Step-by-step explanation:
The given complex number is:

Firstly we can solve (2+3i)(4-7i)(1+i)
= 2(8)+2(-7i)+4(3i)+3i(-7i²)× (1+i)
= (16-14i+12i-21i²i)× (1+i)
Since, i² = -1
= (16-14i+12i-21(-1)i)× (1+i)
= (16-14i+12i+21)× (1+i)
= (29-2i)(1+i)
= 31+27i
Denominator : (1-i²)
= (1-(-1))
= 2

Hence, the correct answer is
.
Answer:
x^2+2xh+h^2+2
Step-by-step explanation:
F(x+h)=(x+h)^2+2 = x^2+2xh+h^2+2.
Answer:102
Step-by-step explanation: First, you need to add (7+5) 7+5 is 12. Now you have 12/6+10^2. You do 10^2 next. 10^2=100. 12/6+100. You divide 12 by 6. 12/6 is 2. 2+100 is left. 2+100 is 102.
