Best ResponseYou've already chosen the best response.0remember that \( 9^2 \) means \( 9 \cdot 9\) and \(9^6 \) means \( 9 \cdot 9\cdot 9\cdot 9\cdot 9\cdot 9\) and when you multiply them you get \( 9 \cdot 9 \cdot 9 \cdot 9\cdot 9\cdot 9\cdot 9\cdot 9\) and you can use the "short way" by writing 9 with what as the little number in the upper right ? (to find the number, count the number of nines)

Best ResponseYou've already chosen the best response.0the first one give me=56 second=4 third=20 fourth=0

Best ResponseYou've already chosen the best response.0Do you know how to write \[ 9 \cdot 9 \cdot 9 \cdot 9\cdot 9\cdot 9\cdot 9\cdot 9 \] using 9 with a little number in the upper right ?

Best ResponseYou've already chosen the best response.0so those are the answers you get to choose from right

phi

Best ResponseYou've already chosen the best response.0to answer this question, you need to learn what the exponent (little number in the upper right) means examples: \[ 9^1 = 9 \\ 9^2 = 9 \cdot 9 \\ 9^3= 9 \cdot 9 \cdot 9 \] do you get that idea ? the little number tells you how many times 9 is multiplied by itself

phi

Best ResponseYou've already chosen the best response.0they start with \[ 9^2 \cdot 9^6 \] if we change to the "long way" to write that, it is \[ 9 \cdot 9 \ \cdot \ 9 \cdot 9\cdot 9\cdot 9\cdot 9\cdot 9 \]

phi

Best ResponseYou've already chosen the best response.0now change the "long way" to the short way. Can you do that for \[ 9 \cdot 9 \cdot 9 \cdot 9\cdot 9\cdot 9\cdot 9\cdot 9 \] ?

Best ResponseYou've already chosen the best response.0\[\huge x^n \times x^m \implies x^{n+m}\] \[\huge \frac{ x^n }{ x^m } = x^{nm}\] I think that's more clear now.
