Question

16^5 +2^15 is divisble by-
(a) 31 (b) 13 (c) 27 (d) 33

Answer 1

Answer: (d)

As we are given the exponents

We have to factor out

$16^5+2^{15}=(2^4)^5+2^{15}=2^{20}+2^{15}=2^{15}(2^5+1)$

If we simplify it

We get $2^{15}(33)$

And it will be divisible by 33.

Answer 2

the answer is D.. 33...
