An exponent.
The exponent for 8^2 is 2. In this case, the number 2 represents the power to which the base number 8 is raised. When 8 is raised to the power of 2, it equals 64. Exponents indicate how many times a number is multiplied by itself.
In exponential form, 64 can be expressed in at least four ways. These are 64 raised to the first power, 2 raised to the sixth power, 4 raised to the fourth power, and 8 raised to the second power.
Horsepower is not measured in litres. Litres is a measure of engine displacement, not power. Power is roughly proportional to displacement, but also varies with many other factors.
3^2
It is the exponent and tells you how many times the base is to be multiplied.
6421 cubic cm = 6.421 litres.
1m*2m*15cm = 0.3 metres3 = 300 Litres
In index form, 250 can be expressed as 5^3. This is because 5 multiplied by itself three times (5 x 5 x 5) equals 250. Index form is a way to represent a number as a base raised to a power, where the power indicates how many times the base is multiplied by itself.
28 to the 2nd power
4 to the third power multiplied by 4 to the 5th power can be written as (4^3)x(4^5) When a number is raised to a power, it means that that number is multiplied by itself as many times as the power denotes. For example, 2 cubed, or 2^3, is two multiplied by itself three times. 2^3=2x2x2=8 In this case, (4^3)x(4^5)=(4x4x4)x(4x4x4x4x4) As you can see, this is the same as multiplying 4 by itself 8 times, or 4^8. At this point, the only way to know the answer is to multiply 4 by itself 8 times. 4x4x4x4x4x4x4x4=65,536 65,536 is your answer.
