sederhanakan dan tuliskan jawaban dalam bentuk baku a. (5x10^2) x (3x10^3) b. (7,2x10^-3) x (4x10^5) c. (5.25x10^6) x (10^-12) d. (1,25x10^16) / 5x10^6 e. 1,6x1

a.
(5 × 10^2) × (3 × 10^3)
= (5 × 3) × (10^2 × 10^3)
= 15 × 10^5
= 1,5 × 10^6

b)
(7,2 × 4) × (10^(-3) × 10^5)
= 28,8 × 10^2
= 2,88 × 10^3
c)
(5,25) × (10^6 × 10^(-12))
= 5,25 × 10^(-6)

d)
(1,25/5) × (10^16/10^6)
= 0,25 × 10^10
= 2,5 × 10^9

e)
(1,6/2) × (10^(-3)/10^4)
= 0,8 × 10^(-7)
= 8 × 10^(-8)
