Question

repedeeeee,va rog eu dau coroană ​

Answer 1

a) [9²+9×(5²-3+2³+7)]:3²

=[81+9×(25-3+8+7)]:9

=[81+9×(22+15)]:9

=(81+9×37):9

=(81+333):9

=414:9

=46

b) 10² : [(2²+2³):12+3³:3]

= 100 : [(4+8):12+27:3]

= 100 : (12:12+27:3)

= 100 : (1+9)

= 100 : 10

= 10

c) [7²³ × (1+7⁰+5³:25)] : 7²²

= [7²³ × (1+1+125:25)] : 7²²

= [7²³ × (1+1+5)] : 7²²

=(7²³ × 7) : 7²²

=7²⁴ : 7²²

=7²

=49

d) [2⁰+2¹+3¹⁴:(3×3¹²)]²:3²

= (1+2+3¹⁴:3¹³)²:9

=(1+2+3¹⁴:3¹³)²:9

=(1+2+3¹):9

=9:9

=1
