1.(-7a²)²2.(8a²b⁴)³3.(-4p³q²r)³

Jawaban:

بِسْمِ اللَّهِ الرَّحْمَنِ الرَّحِيم

1.(-7a²)² = -7a⁴

2.(8a²b⁴)³ = 8^3a^6

$1. {( - 7 {a}^{2} )}^{2} = { - 7}^{2} {a}^{2 times 2} = 49 {a}^{4}$

$2. {(8 {a}^{2} {b}^{4} ) }^{3 } \ = {8}^{3} {a}^{2 times 3} {b}^{4 times 3} \ = 512 {a}^{6} {b}^{12}$

3.(-4p³q²r)³= -4p^6 q^5 r^4

$({ - 4 {?}^{?} }^{?}$

ingat: untuk operasi perkalian maka variabel yang sama, pangkatnya di jumlah
