Answer 2

The correct answer is 2.

Given: The equation = $121=100(1+\frac{10}{100} )^{x}$.

To Find: The value of x.

Solution:

$121=100(1+\frac{10}{100} )^{x}$

$\frac{121}{100} =(1+\frac{10}{100} )^{x}$

$(\frac{11}{10} )^{2} =(1+\frac{10}{100} )^{x}$

$(\frac{11}{10} )^{2} =(1+\frac{1}{10} )^{x}$

$(\frac{11}{10} )^{2} =(\frac{10+1}{10} )^{x}$

$(\frac{11}{10} )^{2} =(\frac{11}{10} )^{x}$

As the base is same. So we can compare powers.

x = 2

Hence, the value of x is 2.
