Question

Could someone help me with this math problem?

Answer 1

729

Explanation:

1/3^-2×3^-4×(-1)^2

=3^2×3^4/1

=9×81

=729

Answer 2

For this case we have the following expression:

`\frac {1} {3^ {- 2} * x^( - 4) * y ^ 2}`

We must evaluate the expression to:

`x = 3\\y = -1`

So:

`\frac {1} {3^(- 2) * 3^( - 4) * (- 1) ^ 2} =`

`\frac {1} {\frac {1} {3 ^ 2} * \frac {1} {3 ^ 4} * 1} =\\\frac {1} {\frac {1} {3 ^ 2} * \frac {1} {3 ^ 4}} =\\\frac {1} {\frac {1} {9} * \frac {1} {81}} =\\\frac {1} {\frac {1} {729}} =\\\frac {729} {1} =\\729`
