Question

[3,2+2,5X(10-8,9)-0,19X5]²X(6,25-1,5²)

Answer 1

= [ 3,2 + 2,5 x 1,1 - 0,95]^2 x 6,25 - 2,25 = 
[3,2 + 2,75 - 0,95]^2 x 4 =
5^2 x 4 =
25 x 4 = 
=100 

Answer 2

[3,2+2,5×(10-8,9)-0,19×5] la puterea 2 ×(6,25-1,5 la puterea 2)=
=(3,2+2,5×1,1-0,95) la puterea 2 ×(6,25-2,25)
=(3,2+2,75-0,95) la puterea 2 ×4
=(5,95-0,95) la puterea 2 ×4
=5 la puterea 2 ×4
=25×4
=100
