Question

how we can find the value of the variable in algebra for class 6​

Answer 1

Answer:

Variable: A letter or symbol that represents any member of a collection of two or more numbers is called a variable.

Constant: A letter or a symbol that represents a specific number is called a constant or else a symbol having a fixed numerical value is called a constant.

The letters which are used to represent numbers are called literals or literal numbers

Multiplication Property : X × Y = XY

Example 5 × X = 5X

a × a × a ×….× 11 times = $a^1^1$ times

In $x^9$, where 9 is called the index or exponent, and x is called the base.

The operations used in algebra are addition, subtraction, multiplication and division.

Addition : x + y

Subtraction : x – y

Multiplication: It is represented in either of the forms, such as xy or x.y or x(y) or (x)(y)

Division : x/y or x÷y or  $\frac{x}{y}$ or $\sqrt[y]{x}$
