Question

14(0.89)^x+4.5 =162

Answer 1

`14(0.89)^(x + 4.5) = 162`

`(14(0.89)^(x + 4.5))/(14) = (162)/(14)`

`0.89^(x + 4.5) = 11(4)/(7)`

`ln(0.89^(x + 4.5)) = ln(11(4)/(7))`

`(x + 4.5)ln(0.89) = ln(11(4)/(7))`

`((x + 4.5)ln(0.89))/(ln(0.89)) = (ln(11(4)/(7)))/(ln(0.89))`

`x + 4.5 = -2101.14032500`

`x = 2105.64032500`
