Question Simplify the expression 2n−1 Evaluate 2(n×1)−1Remove the parentheses 2n×1−1Solution 2n−1 Show Solution Find the roots n=21Alternative Form n=0.5 Evaluate 2(n×1)−1To find the roots of the expression,set the expression equal to 0 2(n×1)−1=0Any expression multiplied by 1 remains the same 2n−1=0Move the constant to the right-hand side and change its sign 2n=0+1Removing 0 doesn't change the value,so remove it from the expression 2n=1Divide both sides 22n=21Solution n=21Alternative Form n=0.5 Show Solution
