For Option 1: "The expression $\left({\mathit{x}}^2+10\mathit{x}+25\right)$ cannot be simplified further" - This option is true because the expression is already in its simplest form, though it can be factored as ${\left(\mathit{x}+5\right)}^2$.
For Option 2: "The value of the variable in an equation which satisfies the equation is called a solution of the equation" - This option is true because the solution of an equation is defined as the value(s) of the variable(s) that make the equation true.
For Option 3: The given expression $3+4\times 5$ is a mathematical expression. So this is not true.
Option 4: "Operations of multiplication can be done on mathematical expressions" - This option is true because multiplication is a valid operation that can be performed on mathematical expressions.
