A(3 , 4) — sb X —> A'(3 , -4)
B(5 , 4) — sb X —> B'(5 , -4)
C(-6 , 5) — sb X —> C'(-6 , -5)

P(3 , -2) — [O , k] —> P'(9 , -6)
k = xP'/xP atau k = yP'/yP
k = 9/3 atau k = -6/(-2)
k = 3 atau k = 3
Q(-2 , 3) — [O , 3k]
—> Q(-2 , 3) — [O , 3(3)]
—> Q(-2 , 3) — [O , 9]
—> Q'(-2(9) , 3(9))
—> Q'(-18 , 27)

P(4 , 4) — [O , 45°] berlawanan arah jarum jam
=> P(4 , 4) — [O , 45°] –> P'((1/2)V[2(4)] – (1/2)V[2(4)] , (1/2)V[2(4)] + (1/2)V[2(4)])
=> P(4 , 4) — [O , 45°] –> P'(1/2[2V2] – 1/2[2V2] , 1/2[2V2] + 1/2[2V2])
=> P(4 , 4) — [O , 45°] –> P'(V2 – V2 , V2 + V2)
=> P(4 , 4) — [O , 45°] –> P'(0 , 2V2)

(1/8)^8 : (1/4)^5 × (1/2)^2
= (1/(2^3))^8 : (1/(2^2))^5 × (1/2)^2
= (2^-3)^8 : (2^-2)^5 × (2^-1)^2
= (2^-24) : (2^-10) × (2^-2)
= 2^(-24 – (-10) + (-2))
= 2^(-24 + 10 – 2)
= 2^-16
= 1/(2^16)
= 1/65536
