WebWhen taking square roots the answer can either be a positive or negative number, so we use the plus or minus symbol to represent that. Which value we use actually depends on the problem we are doing. If say, we are calculating a value for something like 'years since 2000' then that value can only be positive. WebWe can then take cube roots of both sides of the equation, where we note (1 5 − 3 𝑥) = 1 5 − 3 𝑥 and √ 2 7 = 3. Hence, 1 5 − 3 𝑥 = 3. We can now solve for 𝑥. We subtract 15 from both sides of the equation to get − 3 𝑥 = − 1 2. Then, we divide through by − 3 to get 𝑥 = 4. did popular sovereignty work out
