Hi

My nane is Floren and I am a secondary student. Could you help me to solve this exercise?: The numbers 2¹⁹⁸⁹ and 5¹⁹⁸⁹ are written one after another. How many digits in all are there?

Thanks for your help in advance.

Floren,

Ask yourself how you can estimate the number of digits of a number by taking its logarithm in base 10.
