f(n) = 90^n – n × 1/n
f(2) = ??
lg skt ..
Q.
f(n) = 90ⁿ – n × 1/n
f(2) = 90² – 2 × 1/2
f(2) = 90(90) – 2 × 1/2
f(2) = 8.100 – 2 × 1/2
f(2) = 8.100 – 2/2
f(2) = 8.100 – 1
f(2) = 8.099
:)
Penjelasan dengan langkah-langkah:
Jawaban :
f(2) = 90² – 2 × 1/2
f(2) = 8.100 – 2 × 1/2
f(2) = 8.100 – 2/2
f(2) = 8.100 – 1
f(2) = 8.099
I hope this help :)
