Question

3^2x+5=2187 find the value of x​

Answer 1

3^(2x + 5) = 2187

(3^2x)*(3^5) = 3^7

3^2x = 3^7/3^5

3^2x = 3^2

2x = 2

x = 1 ——> Answer

Answer 2

Answer:

3^2x+5 =2187=

Step-by-step explanation:

first write this eq. 3^2+5 =2187

second factor 2187 in form of three and solve

3^2x+5 = 3^7

when base same then power will be equal then

2x+5 =7

in this side five in add gone that side it will be

in subtract therefore

2x =  7-5

2x = 2

then 2 in mulitple go in that side will be in /

x= 2/2

x = 1    ans≈
