Answer 2

Answer:

X =80

Step-by-step explanation:

$\red{ \bf{ \underline{correction \: the \: QUESTION \:}}}$

$\large{ \sf{ {4}^{20} + {4}^{20} = {2}^{x} }}$

find the value of x

═════════════════════════════

$\star{ \pink{ \underline{ \underline{Ｓｏｌｕｔｉｏｎ \: : - }}}}$

$: \implies \large{ \purple{ {2}^{20 \times 2} + {2}^{20 \times 2} = {2}^{x}}}$

$: \implies \large{ \purple{ {2}^{40} + {2}^{40} = {2}^{x}}}$

$\sf{ \underline{if \: the \: base \: is \: same \: than \: the \: power \: can \: be \: added \: or \: substrared}}$

SO,

$: \implies \large{ \purple{ {2}^{40 + 40} = {2}^{x}}}$

$: \implies \large{ \purple{ {2}^{80} = {2}^{x}}}$

$: \implies \large{ \purple{x = 80}}$
