solve 5^x=50

OpenStudy (anonymous):

x ≈ 2.43 x ≈ 4.56 x ≈ 3.89 x ≈ 1.67

OpenStudy (phi):

you could test each choice. or you can solve by taking the log of both sides

OpenStudy (anonymous):

5^x=50 you take logarithm with base 5 x=log(5,50)

OpenStudy (anonymous):

how do i solve that?

OpenStudy (aum):

5^x = 50 Let us try x = 1, 2, 3 x = 1, 5^1 = 5 x = 2, 5^2 = 25 x = 3, 5^3 = 125 5^x = 50. 25 < 50 < 125 Therefore, 2 < x < 3

OpenStudy (anonymous):

You have to plug it in to get the exact number. or aproximation as the one above

OpenStudy (aum):

There is only one answer choice for x between 2 and 3.

OpenStudy (anonymous):

so x=2.43

OpenStudy (aum):

Yes.
