Book Free DemoNow we have to find out the values of algebraic expressions using the given variables.
Steps to find the value of the algebraic expression:
Step \(1\): Understand the problem first and then fix the variable and write the algebraic expression.
Step \(2\): Substitute each variable by the given numerical value to get an arithmetical expression.
Step \(3\): Try to solve or simplify the arithmetical expression by the BIDMAS method.
Step \(4\): Now, the final value you obtained is the required value of the expression.
Example:
Question I)
Consider the algebraic expression and the value of \(m=\) 12 and \(n=\) 4.
Consider the algebraic expression and the value of \(m=\) 12 and \(n=\) 4.
Now substitute the values of \(m\) and \(n\), we get
Therefore, the value of the algebraic expression \(=\) 112.
Question II)
Consider the algebraic expression with the value of \(m=\) 12 and \(n=\) 4.
Consider the algebraic expression with the value of \(m=\) 12 and \(n=\) 4.
Now substitute the values of \(m\) and \(n\), we get
Therefore, the value of the algebraic expression \(=\) 84.
Question III)
Consider the algebraic expression is with the value of \(m=\) 12 and \(n=\) 4.
Consider the algebraic expression is with the value of \(m=\) 12 and \(n=\) 4.
Now substitute the values of \(m\) and \(n\), we get
Therefore, the value of the algebraic expression \(=\) 147.
