barisan aritmatika
bilangan ganjil 2 digit
11, 13, 15, 17, … , 99
a = 11
b = 13 – 11 = 2
n = (Un – a)/b + 1
n = (99 – 11)/2 + 1
n = 44 + 1
n = 45
Sn = n/2 (a + Un)
S45 = 45/2 (11 + 99)
S45 = 45/2 × 110
S45 = 45 × 55
S45 = 45(50 + 5)
S45 = 2250 + 225
S45 = 2475

((2a⁵b) / (16a²b⁴))^-1
= (16a²b⁴) / (2a⁵b)
= 16/2 . a²/a⁵ . b⁴/b
