I am  using the laws:
1) ( x^{a} )^{c} = x^{a*c}
2) x^{a} * x^{b}  =  x^{a+b}
3) \frac{ x^{a} }{x^{b}} = x^{a-b}

an x is a base - the law is valid if the bases are the same number!

The solution in attachment :)

PLEASE HELP, Erika is working in solving the exponential equation 50^x = 17 ; however, she is not quite sure where to start. Usi
Furkat [3]

Yes, 50^x = 17 is an exponential equation with base 50, and the task here is to solve it for x.

1) Take the log of both sides:  x log 50 = log 17

2) Divide both sides b log 50:    

      log 17

x = ----------

      log 50

3)  This last result can't be simplified, but can be evaluated"

x = 1.2304 / 1.6990 = 0.724 (approx.)

lesya692 [45]

Answer:

45 premium tickets were sold

Step-by-step explanation:

p = premium

d = deluxe

r = regular

p+d+r = 273

6p+4d + 2r = 836

118+d = r

Replace r with 118+d

p+d+118+d = 273

p +2d = 273-118

p+2d = 155

6p+4d + 2(118+d) = 836

6p+4d + 236+2d = 836

6p +6d = 836-236

6p + 6d = 600

Divide by 6

p+d = 100

d = 100-p

Replace d in p +2d= 155

p +2(100-p) = 155

p+200-2p = 155

-p = 155-200

-p =-45

p =45

45 premium tickets were sold
