Work: Calculate the value of equation 8*(8*(8*(8*(8+1)+1)+1)+1)-6*(6*(6*(6*(6+1)+1)+1)+1)-1 .
Question type: Mathematical calculation
Solution:
8*(8*(8*(8*(8+1)+1)+1)+1)-6*(6*(6*(6*(6+1)+1)+1)+1)-1
=8*(8*(8*(8*9+1)+1)+1)-6*(6*(6*(6*(6+1)+1)+1)+1)-1
=8*(8*(8*73+1)+1)-6*(6*(6*(6*(6+1)+1)+1)+1)-1
=8*(8*585+1)-6*(6*(6*(6*(6+1)+1)+1)+1)-1
=8*4681-6*(6*(6*(6*(6+1)+1)+1)+1)-1
=8*4681-6*(6*(6*(6*7+1)+1)+1)-1
=8*4681-6*(6*(6*43+1)+1)-1
=8*4681-6*(6*259+1)-1
=8*4681-6*1555-1
=37448-6*1555-1
=37448-9330-1
=28118-1
=28117 Answer:8*(8*(8*(8*(8+1)+1)+1)+1)-6*(6*(6*(6*(6+1)+1)+1)+1)-1=28117[3/3 Formula]
Work: Calculate the value of equation (1*1+2*2+3*3+4*4+5*5+6*6+7*7+8*8+9*9+10*10)/(1+2+3+4+5+6+7+8+9+10)*7 .
Question type: Mathematical calculation
Solution:
(1*1+2*2+3*3+4*4+5*5+6*6+7*7+8*8+9*9+10*10)/(1+2+3+4+5+6+7+8+9+10)*7
=385/(1+2+3+4+5+6+7+8+9+10)*7
=385/55*7
=7*7
=49 Answer:(1*1+2*2+3*3+4*4+5*5+6*6+7*7+8*8+9*9+10*10)/(1+2+3+4+5+6+7+8+9+10)*7=49Your problem has not been solved here? Please go to the Hot Problems section!
