1. Jawaban Spora
a. [tex] \frac{2}{5} ^{-4}[/tex] x [tex] \frac{2}{5} ^{3}[/tex] = [tex] \frac{2}{5} ^{-1}[/tex]
b. ([tex] \frac{2}{4} + \frac{3}{5} [/tex])⁻² = -
2. Jawaban junitanjung
a.(2/5)^(-4+3)=(2/5)^(-1)=1/(2/5) atau 5/2
b.1/(2/4+3/5)²=1/((10+12)/20)²=1/(22/20)²=1/(11/10)²=1/(121/100)=100/121
