1/81 is my answer for this...

oh you mean 3^-4

  • triciaal
correct

yaay!! swaggy <3

yes
anonymous
  • anonymous
ok how do u do this?
triciaal
  • triciaal
you can shift the number 6 to get the symbol for exponent

3^(-4)=1/3^4=1/81
anonymous
  • anonymous
ok how does that work? like what does it look like
Nnesha
  • Nnesha
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
anonymous
  • anonymous
ok
Nnesha
  • Nnesha
that's how \[\huge\rm \frac{ x^{-m} }{ 1 }=\frac{ 1 }{ x^m }\]

ok

what about somthing like this What is the value of the expression\[\frac{ 1 }{ 5-^5}\] ?
Nnesha
  • Nnesha
`flip` it
triciaal
  • triciaal
when you subtract exponents you are dividing numbers/variables with the same base. anything to the zero is 1
anonymous
  • anonymous
then it would look like this \[5^-5\]
anonymous
  • anonymous
right?

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

ok what is the answer What is the value of the expression 1/5^5 ?
anonymous

4^5?

it's \[\large\rm \frac{ 1 }{ 5^{-5} }\]
