Q. ( spesial ultah gw :V )
Penjelasan dengan langkah-langkah:
mohon maaf jika salah Terima kasih selamat ulang tahun
Nomor 1
f(x) = 50x – 100 + 8
f(5) = 50(5) – 100 + 8
= 250 – 100 + 8
= 150 + 8
= 158
Nomor 2
70² + 5 – 3
= (70 × 70) + 5 – 3
= (7 × 10 × 7 × 10) + 5 – 3
= (49 × 100) + 2
= 4.900 + 2
= 4.902
Nomor 3
20 × 5
= 100
