In the mark scheme they have done
P = (8×1013) × 5.3 ×106(1.6 × 10-19) = 67.8 W
I don't understand why they have done this?
How does Activity x Energy= Power ?

"Activity" (in Bq) is the number of nuclei that decay per second.
"Energy" is defined as the energy per nucleus released. As defined in the answer here, the units after the conversion will be in joules (MeV * 1.6 × 10-19 = Joules).
Hence,
(number of nuclei / second)*(joules / number of nuclei) = (joules / second) = watts
Make sense?
