9^x + 3^1 ^+ ^2x = 50
(a) Find the exact solution of the exponential equation in terms of logarithms.
9^x+3 and everything past 3 is the exponent 1+2x is the exponent and it all equals 50. Find the exact solution of the exponential equation in terms of logarithms.
+37146 I think this?
9x + 31+2x = 50
32x + 31+2x
32x +3 * 32x
4* 32x = 50
32x = 50/4 = 12.5 take logs of both sides
2x log 3 = log 12.5
2x = log12.5/log3
x = 1.1495
