Question

What power of -3 is 729

Answer 1

Answer:

6

Step-by-step explanation:

Question is

${ - 3}^{x} = 729$

729 can be written as 3⁶

${ - 3}^{x} = {3}^{6}$

For this we need to understand

Eg:

(-2)²=4 ; (-2)³=-8

-x to the power of odd value = -

-x to the power of even value = +

Then 6 is even

So,

3⁶=(-3)⁶

${ - 3}^{x} = { - 3}^{6}$

If bases are same then equate powers

x=6

Therefore x=6

(-3)⁶=729
