Is is called the exponent.
Base of a power
colol\the base
The base is the repeated factor, the exponent is the number of times by which the base is mutltiplied by itself. The exponent is also known as the power, althought the product of the exponential expression can also be described as the power.
An exponential or power term.
16
power
In a power expression, you have two numbers.The number written normally (to the left) is called the BASE. That's what tells you what factor you should multiply by itself. The small raised number (to the right) tells you how often the factor is used. It's called the EXPONENT.

eithth to the eighth power is 376
9 to the eighth power = 43046721
192 to the eighth power is 1,846,757,322,198,614,016
3 dB is a change in power by a factor of 2. If it is plus, i.e. +3dB, power is doubled. If it is minus, i.e. -3dB, power is halved. 6 dB, then is a factor of four, or quarter; 6 dB is a factor of eight, or eighth, etc. The actual equation is 3 log2 (POWER OUT / POWER IN).
The base is the repeated factor, the exponent is the number of times by which the base is mutltiplied by itself. The exponent is also known as the power, althought the product of the exponential expression can also be described as the power.
Nine to the eighth power (98) is 43,046,721
In the expression 45 the 4 is the base and the 5 is the exponent.
