What is indices in maths and examples?
Index (indices) in Maths is the power or exponent which is raised to a number or a variable. For example, in number 24, 4 is the index of 2. The plural form of index is indices. In algebra, we come across constants and variables. The constant is a value which cannot be changed.
What are the laws of indices?
Index laws are the rules for simplifying expressions involving powers of the same base number. = ( 3 √ 27)2 = (3)2 = 9. (2) Watch out for powers of negative numbers. For example, (−2)3 = −8 and (−2)4 = 16, so (−x)5 = −x5 and (−x)6 = x6.
What are indices in algebra?
How do you solve indices with variables?
For example, to solve 2x – 5 = 8x – 3, follow these steps:
- Rewrite all exponential equations so that they have the same base. This step gives you 2x – 5 = (23)x – 3.
- Use the properties of exponents to simplify. A power to a power signifies that you multiply the exponents.
- Drop the base on both sides.
- Solve the equation.
What are the CIE GCE O Level Additional Mathematics questions?
In most of the cases, the question you encounter in your CIE GCE O Level Additional Mathematics questions is a mixture of multiplication and division of numbers with different indices in a form of equation. Such an example is shown below.
