2^x-1 2^x 1 =1280 please solve it?
Solving 2^x-1 * 2^x = 1280



  • Step 1: Use the rule of exponents to simplify the left-hand side of the equation


    • 2^x-1 * 2^x = 2^(x-1) * 2^x = 2^(x-1+x) = 2^(2x-1)


  • Step 2: Substitute the simplified expression back into the original equation


    • 2^(2x-1) = 1280


  • Step 3: Rewrite 1280 as a power of 2 using the rule of exponents


    • 1280 = 2^10


  • Step 4: Substitute 2^10 for 1280 in the equation


    • 2^(2x-1) = 2^10


  • Step 5: Equate the exponents on both sides of the equation


    • 2x-1 = 10


  • Step 6: Solve for x


    • 2x = 11

    • x = 5.5




Final Answer: x = 5.5


Explanation: To solve the equation, we first simplified the left-hand side using the rule of exponents. We then substituted the simplified expression back into the original equation and rewrote 1280 as a power of 2. Equating the exponents on both sides of the equation allowed us to solve for x, which turned out to be 5.5.
