Answer 2

Answer:

Step-by-step explanation:

4^20 + 4^20 = 2^x

=   2(4^20) = 2^x                   ( as a+a=2a)

= 2(2^40) = 2^x                     ( as 4 is 2^2 so (2^2)20 )

= 2^1 X 2^40= 2^x                     (as 2 = 2^1)

= 2^41=2^x

:.  We know when bases are equal powers are also equal

hence,

x=41

Please mark me the brainiest answer.

Thank you.
