Exponents and Powers. The expression of repeated multiplication of a factor is power. Exponent represents the number of times a factor is multiplied to itself. Learn in detail at BYJU’S.
Question 4: What are the 7 different laws of exponents? Answer: The 7 different laws of exponents are as follows: Multiplying the powers with equal base. Dividing the powers with a similar base. Power of a power. Multiplying the powers with similar exponents. Negative (-) Exponents. Power ...
-3 = x 2 . x 3 by using the laws of exponents , we can add the exponents if the base values are the same. thus, x 2 . x 3 = x (2+3) hence, x 2 /x -3 = x 5 also, read: reciprocal integers as exponents exponents and powers class 7 how to multiply negative exponents?
Many arithmetic operations like addition, subtraction, multiplication, and division can be conveniently performed in quick steps using the laws of exponents. These rules also help in simplifying numbers with complex powers involving fractions, decimals, and roots.Let us learn more about the different ...
Laws ExplainedThe first three laws above (x1 = x, x0 = 1 and x-1 = 1/x) are just part of the natural sequence of exponents. Have a look at this:Example: Powers of 5 .. etc.. 52 1× 5 × 5 25 51 1× 5 5 50 1 1 5-1 1÷ 5 0.2 5-2 1÷ 5 ÷ 5 0.04 .. etc...
