    you can shift the number 6 to get the symbol for exponent

    3^(-4)=1/3^4=1/81

    exponent rule \[\huge\rm x^{-m}=\frac{ 1 }{ x^m }\] when you see negative exponent you should flip the fraction to make it positive exponent

    that's how \[\huge\rm \frac{ x^{-m} }{ 1 }=\frac{ 1 }{ x^m }\]

    what about somthing like this What is the value of the expression\[\frac{ 1 }{ 5-^5}\] ?

    `flip` it

    when you subtract exponents you are dividing numbers/variables with the same base. anything to the zero is 1

    then it would look like this \[5^-5\]

    with practice you can like @Nnesha said "flip it" AND change the sign

  25. Nnesha

    when you do that sign would change \[\huge\rm x^{\color{reD}{-m}}=\frac{ 1 }{ x^\color{reD}{m} }\] why do we have to flip it ? so we can change negative to positive exponent
