Question

solve the exponential equation ,


(3)^x +2 = 7

log 3 ^ x +2 = log 7

x + 2 log 3 = log 7

whats next ?

Answer 1

divide both sides by log3

Answer 2

x + 2 = log 7 / log 3

Answer 3

now subtract 2 from both sides

Answer 4

x = (log 7/ log 3 ) -2 correct?

Answer 5

you can do like this
3^x + 2 = 7
3^x = 5
x = log(5)/log(3)

Answer 6

yes its correct. its the value of x. @yamyam70

Answer 7
