Question

4^-x =1/6 find x
need help asap​

Answer 1

x = 2
This is because when you have a negative exponent like -x to rearrange it to a fraction and change the negative to a positive.
So 4^x would be the denominator and 1 would be the numerator.
So 1 / 4^x = 1 / 16
To achieve 16 from 4 you square it, therefore x = 2

Answer 2

2

Explanation:

you can make it like this

(1/4)^ x=1/16

so x=2
