Question

Observe o modelo e calcule :

a) (25 + 1 ). ( 25-1) = 26.24 = 624
b) 25+ 2 ) • ( 25-2)=
c) (25+3). (25-3)=
d) (25+4). (25-4)=
e) (25+5). (25-5)=

..

Answer 1

a) (25+1) • (25-1) = 26.24 = 624
b) (25+2) • (25-2) = 27.23 = 621
c) (25+3) • (25-3) = 28.22 = 616
d) (25+4) • (25-4) = 29.21 = 609
e) (25+5) • (25-5) = 30.20 = 600

Answer 2

b) (25 + 2) . (25 - 2) = 27 . 23 = 621
c) (25 + 3) . (25 - 3) = 28 . 22 = 616
d) (25 + 4) . ( 25 - 4) = 29 . 21 = 609
e) (25 + 5) . (25 - 5) = 30 . 20 =600
