Question

Solve: 1800(1+10/100)^x = 2178 , find the value of x.​

Answer 1

1800(1+1/10)^x=2178

100(11/10)^x=2178/18

11^x*10^-x=121*10^-2

11^x*10^-x=11^2*10^-2

equating we get,

x=2

Answer 2

1800(1+10/100)x =2178

1800 (100+10/100) x =2178

1800 (110/100) x =2178

1800 (11/10) x =2178

19800/10 x=2178

1980 x=2178

x =2178/1980

x =1.1
