For example, the square root of a number is the same as raising the number to the power of and the cube root of a number is the same as raising the number to the power of . Examples are 4 = 4 1 2 = 2 {\displaystyle {\sqrt {4}}=4^{\frac {1}{2}}=2} and 27 3 = 27 1 3 = 3 {\displaystyle {\sqrt[{3}]{27}}=27^{\frac {1}{3}}=3} .
This was the most advanced number system in the world at the time, apparently in use several centuries before the common era and well before the development of the Indian numeral system. [108] Rod numerals allowed the representation of numbers as large as desired and allowed calculations to be carried out on the suan pan, or Chinese abacus.
One radian is defined as the angle at the center of a circle in a plane that subtends an arc whose length equals the radius of the circle. [6] More generally, the magnitude in radians of a subtended angle is equal to the ratio of the arc length to the radius of the circle; that is, =, where θ is the magnitude in radians of the subtended angle, s is arc length, and r is radius.
Emissivity of a body at a given temperature is the ratio of the total emissive power of a body to the total emissive power of a perfectly black body at that temperature. Following Planck's law , the total energy radiated increases with temperature while the peak of the emission spectrum shifts to shorter wavelengths.
[155] [156] Save game and profile transfers between Switch consoles were added in the 4.0.0 system update in October 2017, [157] while the 10.0.0 system update in April 2020 allowed most update data, digital games (i.e., downloaded from eShop), and other downloaded content to be swapped between the internal memory and a microSD card.

The electoral system of Albania is constructed upon the principles defined in the constitution and the electoral code. As a parliamentary constitutional republic, Albania implements a regional proportional representation method that allocates seats in the parliament according to the proportion of votes garnered by political parties in a multi-party system.
The Massachusetts Turnpike is informally divided into two sections by MassDOT: the original 123-mile (198 km) "Western Turnpike" extending from the New York state border through the interchange with I-95 and Route 128 at exit 123 in Weston, and the 15-mile (24 km) "Boston Extension" that continues beyond exit 123 through Boston.

The mileage for dual-fuel vehicles, such as E85 capable models and plug-in hybrid electric vehicles, is computed as the average of its alternative fuel rating—divided by 0.15 (equal to multiplying by 6.666)—and its gasoline rating. Thus an E85-capable vehicle that gets 15 mpg on E-85 and 25 mpg on gasoline might logically be rated at 20 mpg.
