All laws of exponents Class 9

So basically exponents or powers denotes the number of times a number can be multiplied. If the power is 2, that means the base number is multiplied two times with itself. Some of the examples are: 3 4 = 3├Ś3├Ś3├Ś3. 10 5 = 10├Ś10├Ś10├Ś10├Ś10. 16 3 = 16 ├Ś 16 ├Ś 16. Suppose, a number 'a' is multiplied by itself n-times, then it is. The exponents can be numbers or constants; they can also be variables. Exponents are generally positive real numbers, but they can also be negative numbers. Laws of exponents: If a and b are any real numbers, and m and n are rational numbers then, a m ├Ś a n = a m+n a m a n = a m-n, m > n. (a m) n = a mn (a m ├Ś b m) = (a ├Ś b) m. a m b m = (a.
