Resposta:

$\textsf{Segue a resposta abaixo}$

Explicação passo-a-passo:

$\mathsf{ 4^{10}+2^{20}=1048576+1048576}$

$\mathsf{4^{10}+2^{20}= 2097152}$

$\begin{array}{r|l}\sf 2097152&\sf2\\\sf1048576&\sf2\\\sf 524288&\sf2\\\vdots&\vdots\\\sf 2&\sf2\\\sf1&\!\!\!\overline{~\:\sf2097152=2^{21}~}\end{array}$

$\boxed{\boxed{\mathsf{4^{10}+2^{20}= 2^{21}}}}\leftarrow\textsf{letra D}$
