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^1= N
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
thank you
(2x2)x2=
I DON'T KNOW THATS WHY IM ASKING !!!!!!!!!
i need help what is the combines mass of 4.5 time 10with power of -3 and 2.8 time 10 with power of -2
To find the combined mass of 4.5 times 10 raised to the power of -3 and 2.8 times 10 raised to the power of -2, you can use the rules of scientific notation.
First, multiply the two numbers together: (4.5 x 10^-3) * (2.8 x 10^-2)
To multiply numbers in scientific notation, you multiply the decimal parts together and add the exponents. So, we have:
(4.5 * 2.8) x 10^(-3 + -2)
Multiply the decimal parts: 4.5 * 2.8 = 12.6
Add the exponents: -3 + -2 = -5
So, the combined mass is 12.6 times 10 raised to the power of -5, written as 12.6 x 10^-5.
