Prove the divisibility of the following numbers:
ratelena [41]

Make use of prime factorizations:

16^5+2^{15}=(2^4)^5+2^{15}=2^{20}+2^{15}

Both terms have a common factor of 2^{15}:

16^5+2^{15}=2^{15}\left(2^5+1\right)=2^{15}\cdot33

- - -

The second one is not true! We can write

15^7+5^{13}=(3\cdot5)^7+5^{13}=3^7\cdot5^7+5^{13}

Both terms have a common factor of 5^7:

15^7+5^{13}=5^7\left(3^7+5^6\right)

Since 30=5\cdot6, and 5\mid5^7, we'd still have to show that 5^6(3^7+5^6) is a multiple of 6. This is impossible, because 6=3\cdot2 and there is no multiple of 2 that can be factored out.

What is the answer tie this problem (show ALL work please and thankyou) 1/3(18+12q)=6(2q-7)
qaws [65]
\frac{1}{3}(18 + 12q) = 6(2q - 7)   Use the Distributive Property on both sides
  6 + 4q = 12q - 42   Subtract 12q from both sides
   6 - 8q = -42          Subtract 6 from both sides
       -8q = -48           Divide both sides by -8
          q = 6
