(11.52*10)+8x=1160x, so = 115.2=1160x-8x = 115.2=1152x = so, x=115.2/1152=.1= So, that means she has (1160*.1) = $116.00 Answer=$116

-1/2

Step-by-step explanation:

x^2- 16^x = 0x^2 = 16^xx^2 = 4^2xx = 4^xlogx = xlog41/x×logx = log4log(x^1/x) = log4x^(1/x) = 4

At this point you can guess and try. And it seems that x = -1/2, lets check:

(-1/2)^(1 /-1/2)= (-1/2)^-2= 2^2= 4

So, this is correct: x= -1/2
