Math - Exponential Notion
posted by Trudy on .
Can someone explain this to me please, I cannot help my son with his homework
Do you mean exponential notation?
y ^ x = "y raised to the x power"
Yep - sorry
what do u need help with?
Yes - I am not remembering how to do powers - etc. can their be a number to the first power, or is that just that number ?
I am not remembering how to do powers - like, can their be a number to the first power or would that just bee the number chosen ?
its like this 3^3 is 3x3x3..... so it goes with any power..... if its 3^3 the first number is the number being multiplyed, second number is the one saying how many times you multiply.
Yes, a number to the first power means
N^2=NxN and so on
By definition, N^0 is 1
N^2 means N squared, or N2
yes that would be... like 4^1 is 4
Thank you very much for your help
