» Pendahuluan
Bilangan bereksponen (berpangkat) dinyatakan dengan:
a × a × a × ....... a × a = aⁿ
Notasi: an dibaca “a pangkat n”
a disebut bilangan pokok (basis)
n disebut bilangan pangkat
Berlaku sifat:
1. pᵃ x pᵇ = pᵃ ⁺ ᵇ,
2. pᵃ : pᵇ = pᵃ ⁻ ᵇ,
3. (pᵃ)ᵇ = pᵃ ˣ ᵇ,
4. (p x q)ᵇ = pᵇ x qᵇ,
5. (p : q)ᵇ = pᵇ : qᵇ,
6. p⁰ = 1,
Contoh soal Eksponen (Berulang-ulang)
= 10⁵
= (10 . 10 . 10 . 10 . 10)
= 100.000
Contoh soal Eksponen (Sederhanakan)
= 14¹² ÷ 14¹¹
= 14(¹²-¹¹)
= 14¹
= 14
Contoh Eksponen (pangkat 2 dan 3)
1² = 1 × 1 = 1
2² = 2 × 2 = 4
3² = 3 × 3 = 9
4² = 4 × 4 = 16
5² = 5 × 5 = 25
6² = 6 × 6 = 36
7² = 7 × 7 = 49
8² = 8 × 8 = 64
9² = 9 × 9 = 81
10² = 10 × 10 = 100
1³ = 1 × 1 × 1 = 1
2³ = 2 × 2 × 2 = 8
3³ = 3 × 3 × 3 = 27
4³ = 4 × 4 × 4 = 64
5³ = 5 × 5 × 5 = 125
6³ = 6 × 6 × 6 = 216
7³ = 7 × 7 × 7 = 34
8³ = 8 × 8 × 8 = 512
9³ = 9 × 9 × 9 = 729
10³ = 10 × 10 × 10 = 1000

» Penyelesaian
= 5 ÷ 4
= 5/4
= 1 ¼
= 1 + ¼
= 1 + 0,25
= 1,25 ☑
–––
= 5²
= 5 × 5
= 5 + 5 + 5 + 5 + 5
= 10 + 5 + 5 + 5
= 15 + 5 + 5
= 20 + 5
= 25 ☑
