(2+3)(2²+3²)(2^4+3^4)(2^8+3^8)(2^16+3^16)
=[(2-3)(2+3)(2²+3²)(2^4+3^4)(2^8+3^8)(2^16+3^16)]/(2-3)
=[(2²-3²)(2²+3²)(2^4+3^4)(2^8+3^8)(2^16+3^16)]/(2-3)
=[(2^4-3^4)(2^4+3^4)(2^8+3^8)(2^16+3^16)]/(2-3)
=[(2^8-3^8)(2^8+3^8)(2^16+3^16)]/(2-3)
=[(2^16-3^16)(2^16+3^16)]/(2-3)
=(2^32-3^32)/(2-3)=-(2^32-3^32)=3^32-2^32
