Question

Efectuează a)(1+2+3)la puterea a 4+5×6×(7+8+9); (2 la puterea a 2×3 la puterea a 2-5 la puterea a 2):11+3 la puterea a doua ×7 la puterea a 2-4 la puterea a 2

Answer 1

a)   ( 1 + 2 + 3 )⁴ + 5 x 6 x ( 7 + 8 + 9 ) = 2016

= 6⁴ + 30 x 24 =

= 1 296 + 720 =

= 2 016

_____________________________________

( 2² x 3² - 5² ) : 11 + 3² x 7² - 4² = 426

= ( 4 x 9 - 25 ) : 11 + 9 x 49 - 16 =

= ( 36 - 25 ) : 11 + 441 - 16 =

= 11 : 11 + 425 =

= 1 + 425 =

= 426

Answer 2

(1+2+3)^4+5*6*(7+8+9)=

=6^4+5*6*24=

=1296+5*144=

=1296+720=

=2016

(2^2*3^2-5^2):11+3^2*7^2-4^2=

=(4*9-25):11+9*49-16=

=(36-25):11+441-16=

=11:11+441-16=

=1+441-16

=442-16

=426
