1 Use the OnetoOne property to solve the equation for x e3x5
1) .Use the One-to-One property to solve the equation for x. e^3x+5 = 36
(2).Solve the logarithmic equation algebraically. Approximate the result to three decimal places.
log3(6x-8) = log3(5x + 10)
(3). Use the properties of logarithms to simplify the expression.
log20 209
(4). Use the One-to-One property to solve the equation for x.
e3x+5 = 36
.
Solution
1. e^(3x +5) = 36
Now as per property : loga(a^x) = x
loge(e^(3x+5) = loge(36)
we can equate the argument insied the log:
(3x +5) = loge(36)
x = (loge(36) -5) )/3
2. log3(6x-8) = log3(5x + 10)
we cam equate the arguments inside the log
(6x-9) = 5x +10
x = 9+10 =19
