Question

10⁴+10³+10²+10¹+10⁰=

Answer 1

$10^4+10^3+10^2+10^1+10^0=10000+1000+100+10+1=11111$

Answer 2

$\mathbf {10^4 + 10^3 + 10^2 + 10^1 + 10^0}$

$\mathbf {10.000 + 1.000 + 100 + 10 + 1}$

$\mathbf {11.000 + 100 + 10 + 1}$

$\mathbf {11.100 + 10 + 1}$

$\mathbf{11.110 + 1}$

$\purple {\mathbf{\boxed{\boxed{11.111}}}}$
