It is called an exponent. Thus if you see 7 with a small number whose value is 5 in the upper right of 7, it means multiply 7 by itself 5 times, in other words it is a short hand notation for 7x7x7x7x7 which yields16807.

The exponent can be negative. So 7 with a -5 in the upper right of 7 means the reciprocal of 7x7x7x7x7 or (1)/(7x7x7x7x7) which yields 0.000059499

The exponent can be a fraction. So 7 with a 1/2 in the upper right of 7 is asking the question "what number multiplied by itself yields 7" or what is the square root of 7. So in this case the value would be 2.64575 roughly.

The exponent can be a negative fraction. So 7 with a -1/2 in the upper right of 7 is asking the question "what is the reciprocal of the square root of 7". The value would be 0.37796 roughly

Hence the small number written in the upper right of a number is a short form widely used in science and mathematics to convey many precise meanings

What is the base and exponent of 125?

If you are referring to the number 125 itself, then 125 is the base, and 1 is the exponent. This would be written as 1251. This number can also be written as 53, as 5 cubed also equals 125. In this case, 5 is the base, and 3 is the exponent. The main integer value is the base, the number to the upper right of it is the exponent. The exponent tells you how many times to multiply the base number by itself to find the answer.

What is an exponent in algebra?

An exponent is the number in the upper right-hand corner of another number that tells if it is squared, cubed, etc. Squaring is like yxy, while cubed is yxyxy, and so on and so forth.


What does base and exponet mean?

Base and exponent are the two parts of a power. The base is the lower left, normal-sized, number. The exponent is the upper-right, small (i.e., superscript) number. For example, in: 34 3 is the base, 4 is the exponent. In the simplest case, a power specifies a repeated multiplication. The base tells you what number to multiply by itself, the exponent tells you how many times to multiply it. Thus, 34 = 3 x 3 x 3 x 3 (that is, multiply 3 by itself, using the number 4 times as a factor)


How do you identify the base and exponent in the expression two to third power?

The base is the large number, and is the number being multiplied; the exponent is the smaller number on the upper right, which says how many times the base is multiplied. 23 says that 2 is multiplied 3 times, so: 2 X 2 X 2. In this case, the base is 2, and the exponent is 3.
