Jawab

=

2 × 10 −6 ∙ 8 × 10 −6
−1
= 9 × 10 9 = 36 × 10
4 × 10 −2

=

−1
= 9 × 10 9 2×10 −6 ∙ −6×10 −6 = −27 × 10
4×10 −2
= +

−1
= 36 × 10 −1 + − 27 × 10 −1 = 9 × 10

=

2 × 10 −6 ∙ 8 × 10 −6
−1
= 9 × 10 9 = 72 × 10
2 × 10 −2

=

−1
= 9 × 10 9 2×10 −6 ∙ −6×10 −6 = −54 × 10
2 × 10 −2
= +

−1
= 72 × 10 −1 + − 54 × 10 −1 = 18 × 10
= ∆ = −

−1
= 18 × 10 −1 − 9 × 10 −1 = 9 × 10
