10 + 10 + 10 + 10 + 10 + 10 + 10 + 108 = 178
One decaliter is equal to 10 liters. The prefix "deca-" denotes a factor of 10 in the metric system, so when you have a decaliter, you have 10 liters. This relationship is consistent with the metric system's base unit conversions, where each prefix indicates a certain power of 10 difference in the quantity being measured.
The prefix micro-, as in micrometre, or microsecond, refers to 10-6, or one millionth, of the whole.
One method is (10×4)+(5×3) = 55 (or mentally add up from left to right).
There is no prefix for "10-3".
The Metric system is based on 10.

There is no special prefix for that factor. There are SI prefixes for powers of 10 (10, 100, 1000, 0.1, 0.01, 0.001), and especially for powers of 1000 (1000, a million, a billion, 1/1000, etc.)
It indicates 10-12 of a unit.
Adding a prefix changes the magnitude of the base unit. The prefix indicates a multiple of 10 by which the base unit is multiplied. Common prefixes include milli- (0.001), kilo- (1000), and mega- (1,000,000).

A 1 unit change in pH corresponds to a 10-fold change in the concentration of hydrogen ions (H+). For example, a solution with a pH of 5 has 10 times more H+ ions than a solution with a pH of 6.
kilo
The SI unit prefix that means one hundred is "hecto-" symbolized as "h". It denotes a factor of 10^2 or 100.
The unit "deca" is used as a prefix in the metric system to represent 10 times a base unit. For example, 1 decameter is equal to 10 meters, and 1 decagram is equal to 10 grams.
1.35 meters. 100 cm = 1 m. 135/100 = 1.35. This displays the inherent usefulness of the metric system as all units and subunits are simply related by powers of 10 and can be readily identified by their prefix. Milli = 1/1000 of a unit Centi = 1/100 of a unit Deci = 1/10 of a unit No prefix = that unit Deca = 10 * that unit Hecto = 100 * that unit Kilo = 1000 times that unit And so on.
