Homework Equations
The Attempt at a Solution
i hv tried for so many times, but i cant find it
the GCD of 1007 and 1703 is 1, so it is possible to find n and m
Homework Statement
find the last digit of 3^101 X 7^202
Homework Equations
The Attempt at a Solution
i have cal. that the last digit is 7 by...:
[147]mod10 X ([3^4]mod10)^25 X ([7^4]mod10)^25 = [7]mod10 X [1]mod10 = [7]mod10
so the last digit is 7
is it correct?
i m thinking of this...
area bounded by x=0, y=0, y=x^2, y=4-x^2 and x=2
why the region bounded by the below three cases are the same
1. x=0, y=0, y=x^2, y=4-x^2
2. y=0, y=x^2, y=4-x^2
3. and x=0, y=x^2, y=4-x^2
but after i add x=2 and compute the bounded region, it's different?
i am just...
