Soal nomor 20
a. (a⁵b³c³/4bc)x(8ac/3bc⁻³)
= 1/4 a⁵b²c² x 8 ab⁻¹c⁴
= 2 a⁶b⁴c⁶
b. 2m⁰ x m²/³
= 2 x m⁽⁰⁺²/³)
= 2 m²/³
c. m³ + 4/m⁻³
= m³ + 4m³ = 5m³
soal nomor 21
a. x³y = (27)³ . 63
= (3³)³ . (3 . 3 . 7)
= 3⁹ . 3² . 7
= 3⁽⁹⁺²⁾ . 7
= 3¹¹ . 7
b. x/√y = 27/√63
= 3³/√(3 . 3 . 7)
= 3³/√(3² . 7)
= 3³/3√7
= 3⁽³⁻¹⁾/√7
= 3²/√7
maaf kalau salah,keep study^^
