5^(2x-1)+5^(x+1)=250
how do you solve?
thank you

x = 2

Step-by-step explanation:

Exponential Equations

Solve:

Separate each exponential:

Operating:

Multiplying by 5:

Rearranging:

Recall that:

Calling

Factoring:

There are two possible solutions:

y=25

y=-50

Since

y cannot be negative, thus:

The solution is:

x = 2

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
