Answer:
n=7
Step-by-step explanation:
(7^2)^4= n^8
We know that a^b^c = a^(b*c)
7^(2*4) = n^8
7^8 = n^8
Since the exponents are the same, the bases must be the same
n=7
we'd do the same as before on this one as well.
if we take 27.99 to be the 100%, what is 12 off of it in percentage?
So we need to isolate the variable. In order to do that, we need to multiply both sides by 5/4.
Why? That's so that 4/5z will be canceled out when multiplied by 5/4 to get just z.
And so, we would get 20 as our answer.
