Let A be a set of natural numbers not to exceed 150 divided by 7 by 3:  \(A=\left\{x\in N;x=7.q+3;q\in N;x\le150\right\}\)

List the elements of A into a series of numbers from small to large

Sum the elements of A

look for natural n for:

a,\(516^n\div516^{13}=516\)

b,\(8^n\div8=64\)

c,\(3427^6\div3427^n=3427^2\)

tính toán:

1 +1 =

2 + 2 =

3 + 3 =
