    Exponential Equations

    SL AA 1.7

    If two exponentials in the same base are equal, their exponents must be equal:

    an=am⇔n=m🚫


    Exponentials can also appear in equations with one or more unknown:

    (21​)x−1=8x+1
    ⇒(2−1)x−1=(23)x+1
    ⇒21−x=23x+3

    Now we can equate the exponents:

    1−x=3x+3⇒x=−21​
