Question

a^b·c^d=abcd,求abcd及解题过程.a,b,c,d∈Z+,a,b,c,d∈(1,9]

Answer 1

num=0;

for a=2:1:9

for b=2:1:9

for c=2:1:9

for d=2:1:9

if a^b*c^d==1000*a+100*b+10*c+d

num=num+1;

an(num,1)=a;

an(num,2)=b;

an(num,3)=c;

an(num,4)=d;

end

end

end

end

end

>> an

an =

2 5 9 2

>>

电脑算出来的可以么?

a=2,b=5,c=9,d=2
