Answer 1

90 zeros

Explanation:

20^50 × 50^20 =

(2×10)^50 × (5×10)^20

= 2^50 × 10^50 × 5^20 × 10^20

= (2^5)^10 × (5^2)^10 × 10^70

= 32^10 x 25^10 × 10^70

= 800^10 × 10^70

= (8×10²) ^10 × 10^70

= 8^10 × 10^20 × 10^70

= 8^10 × 10^90

Answer 2

90

Explanation:

How many zero can be found in the answer and why? Hi, I want to write ^ to designate powers so I will write 50^20 for 50 power of 20. Since no power of two ends with a zero the number of zeros in (50^20)(20^50) is 90.
