求值:2的99次方+2的98次方+2的97次方+2的96次方.+2+1
2的99次方+2的98次方+2的97次方+2的96次方.+2+1 +1 -1
=2的99次方+2的98次方+2的97次方+2的96次方.+2+2 -1
=2的99次方+2的98次方+2的97次方+2的96次方.+4 -1
=.
=2的100次方-1
利用因式分解運算:(-2)101次方+(-2)100次方
“原式=(-2)^100*(-2+1)=-(-2)^100=-2^100
2的99次方+2的98次方+2的97次方+2的96次方.+2+1 +1 -1
=2的99次方+2的98次方+2的97次方+2的96次方.+2+2 -1
=2的99次方+2的98次方+2的97次方+2的96次方.+4 -1
=.
=2的100次方-1
“原式=(-2)^100*(-2+1)=-(-2)^100=-2^100
