Tham khảo câu trả lời từ Trợ lý ảo Lazi To solve the equation, we can start by simplifying the left side: (1/3 + 1/6) * 2^(n+4) - 2^n = 2^14 - 2^10 To simplify the left side, we need to find a common denominator for 1/3 and 1/6, which is 6. So we can rewrite the equation as: (2/6 + 1/6) * 2^(n+4) - 2^n = 2^14 - 2^10 Now we can combine the fractions: 3/6 * 2^(n+4) - 2^n = 2^14 - 2^10 Simplifying further: 1/2 * 2^(n+4) - 2^n = 2^14 - 2^10 Now we can simplify the powers of 2: 2^(n+1) - 2^n = 2^14 - 2^10 To solve for n, we can subtract 2^n from both sides: 2^(n+1) - 2^n - 2^n = 2^14 - 2^10 - 2^n Simplifying: 2^(n+1) - 2^n - 2^n = 2^14 - 2^n - 2^10 Now we can combine like terms: 2^(n+1) - 2^n - 2^n = 2^14 - 2^n - 2^10 2^(n+1) - 2^n - 2^n = 2^14 - 2^10 - 2^n Next, we can simplify the left side: 2 * 2^n - 2^n - 2^n = 2^14 - 2^10 - 2^n 2^n - 2^n - 2^n = 2^14 - 2^10 - 2^n Now we can combine like terms: -2^n = 2^14 - 2^10 - 2^n To isolate n, we can add 2^n to both sides: -2^n + 2^n = 2^14 - 2^10 - 2^n + 2^n Simplifying: 0 = 2^14 - 2^10 Since 2^14 is greater than 2^10, the equation is not possible. Therefore, there is no solution for n that satisfies the equation.
