how many zeros are in the number? 10 to the power of 10 X 10 to the power of 20 X 10 to the power of 30 Explain how you worked out the answer?

10^10 x 10^20 x 10^30=

10000000000 x 100000000000000000000 x 100000000000000000000000000000

10000000000000000000000000000000000000000000000000000000000

so, there are 60 zeros
