Let me know if I'm correct
using power of 10: numerical of 10^2 is 1x10x10 and if multiply the numerical to get the sum in numerical and decimal is 100
You are partially correct. When we say "10 to the power of 2" or 10^2, it means multiplying 10 by itself twice. So, it would be 10 x 10. The calculation here is simply multiplying the numerical values, which gives us 100, as you mentioned.
However, your explanation of "1x10x10" is not entirely accurate. The expression 1x10x10 suggests multiplying the numbers 1, 10, and 10 together. But in this case, we are only dealing with the number 10 raised to the power of 2.
To summarize, 10^2 is equal to 10 x 10, which equals 100.
