What is 125 in the exponential form?

  • Last Updated : 21 Sep, 2021

Exponents and powers are a method to express repeated multiplication of the same number. For eg- 6×6×6×6 can be written as 64 where 6 is the base and 4 is the exponent. It is most commonly used to express the powers of 10 to write a very large number in a convenient manner. For eg- 100000 can be written as 105.

Laws of Exponents

  • To multiply two exponential numbers with the same bases, the exponents are added and the base remains the same. For eg- am × an = am+n
  • When the exponent has another exponent, the base remains the same but the powers are multiplied. 
    For eg- (am)n = am×n
  • To divide two exponential numbers with the same bases, the exponents are subtracted and the base remains the same. 
    For eg- am/an = am-n

What is a Power Notation?

Power notation is a method to express numbers that are very large or very small. For eg- 10000000000000 can be written as 1013 and 0.000000016 can be written as 1.6 × 10-8

Steps to write a number in the power notation:

Step 1: Write the number and do its factorization.

Step 2: Count the number of times the factor is there.

Step 3: Write the exponential number with the number as the base and the number of times it appeared as the power.

What is 125 in the exponential form?

Solution:

Given that the number is 125.

The factors of 125 are 125 = 5 × 5 × 5

The factors appeared for 3 times.

125 = 53

Hence, the power notation of 125 is 53.
