Hello! Let’s start with multiplying them so they will have the same base! 2(2/3) = 4/6
Alright, now let’s divide them!
4/6 / 5/6 equals to 4 / 6 x 6 / 5 which is equal to 24 / 30 but I only see 2/3 times 6 / 5 WHICH IS the same thing tho.
Answer:
Answer b of the first one
answer of q9
Step-by-step explanation:
(x+iy)(2−3i)=4+i
2x−(3x)i+(2y)i−3yi
2
=4+i
Real
2x+3y
+
Imaginary
(2y−3x)
i=4+i
Comparing the real & imaginary parts,
2x+3y=4--------------------------(1)
2y−3x=1----------------------------(2)
Solving eq(1) & eq(2),
4x+6y=8
−9x+6y=3
13x=5⇒x=

y=

∴(x,y)=(
