Question

efecueaza calculul a) 10+4ori 3 la puteria 2 - 7 ori 5- (3+2 la puteria 3 )
c) (10 la putera 2 - 7la puteria 2 + 5 la puteria 4) ori ( 223 la putera 0 + 1 la puteria 1500)

Answer 1

10+4×3²-7×5(3+2³)=10+4×9-7×5(3+8)=10+36-7×5×24=46-840=-794

(10²-7²+5 la a 4)×(223 la 0+1la 1500)=(100-49+625)×(1+1)=(51+625)×2=676×2=1352

Answer 2

10+4x9-7x5-11=10+36-35-11=46-24=22
(100-49+625)x1+1=(51+625)x1+1=676x1+1=676+1=677
