Answer 1

Explicație pas cu pas:

2^2+3^2=4+9=13

2+2^2=2+4=6

2x3^2=2x9=18

1+2+2^2=1+2+4=3+4=9

3^2x2+1=9x2+1=18+1=19

10-2^3=10-8=2

2-40^30:40^30=2-40^0=2-1=1

3x(3^2+3^3)=3x(9+27)=3x36=108

1+2x3^4=1+2x81=1+162=163

(2+3)^2=2^2+3^2=4+9=13

(2x3+5)^2=2^2x3^2+5^2=4+9+25=13+25=38

9^2x2003-81^2=81x2003-6561=642143-6561=635582
