Answer:
1.4 x 10^-5 dm
Step-by-step explanation:
Centimeters (cm) and decimeters (dm) are interconvertible S.I units of length.
- A centimeter is one-hundredth of a meter i.e. 100cm = 1m
- A decimeter is one-tenth of a metre i.e. 10dm = 1m
Based on this, a centimeter is one-tenth of a decimeter i.e. 1dm = 10cm
Hence, to convert 1.4 x 10^-4 cm to dm, we divide the value by 10
= 1.4 x 10^-4 ÷ 10
= 0.00014 ÷ 10
= 0.000014
Convert back to scientific notation by counting the decimal point forward to have: 1.4 x 10^-5
Hence, 1.4 x 10^-4 cm is equivalent to 1.4 x 10^-5 dm.
