Topics Covered in Exercise 1.5 class 9 Mathematics Questions
Ex 1.5 class 9 maths solutions explores the concepts of the laws of exponents for real numbers.
Laws of Exponents for Real Numbers
- Laws of Exponents for Real Numbers
Exponents are utilized to represent the sequential multiplication of a number on its own. For instance, the number 7 is represented as 7^3. The exponent in this example is '3', which indicates the number of times 7 is multiplied. The base value of 7 is the actual number being multiplied. In other words, an exponent or a power indicates how many times a number is to be multiplied. For example, a power of 2 indicates that the base is to be multiplied twice with itself.
The following are the important laws of exponents.
a^m×a^n = a^m+n
a^m/a^n = a^m-n
(a^m)^n = a^mn
a^pb^p = (ab)^p
