1:计算 (2+1)*(2^2+1)*(2^4+1)*(2^8+1)+1 结果等于?2:分解因式 X^2 - 10X + 16
问题描述:
1:计算 (2+1)*(2^2+1)*(2^4+1)*(2^8+1)+1 结果等于?
2:分解因式 X^2 - 10X + 16
答
1、原式=(2-1)(2+1)(2^2+1)...(2^8+1)+1
=2^16 -1+1
=2^16
2、这道题是十字相乘
原式=(x-2)(x-8)
答
1.原式=(2-1)(2+1)(2^2+1)...(2^8+1)+1
=2^16 -1+1
=2^16
2.(x-2)(x-8)
答
1.(2+1)*(2^2+1)*(2^4+1)*(2^8+1)+1
=(2-1)(2+1)*(2^2+1)*(2^4+1)*(2^8+1)+1
=(2^2-1)(2^2+1)(2^4+1)(2^8+1)+1
=(2^4-1)(2^4+1)(2^8+1)+1
=(2^8-1)(2^8+1)+1
=2^16-1+1
=2^16
2.X^2 - 10X + 16 =(X-2)(X-8)
答
1、原式=(2-1)(2+1)(2^2+1)...(2^8+1)+1
=2^16 -1+1
=2^16
2、原式=(x-2)(x-8)
