Question

(0,87,m-0.66m)x10:2:3=0 ; 10x(1,37k-0.12k):5:8=0

Answer 1

(0,87m-0.66m)*10:2:3=0

0.21m*10:2:3=0

2.1m:2:3=0

1.05m:3=0

0.35m=0

m=0/0.35

m=0

 

10*(1,37k-0.12k):5:8=0

10*1.25k:5:8=0

12.5k:5:8=0

2.5k:8=0

5/16k=0

k=0/(5/16)
k=0

Answer 2

I'm sorry, but the notation you provided is unclear and doesn't seem to make sense mathematically.

In the first expression, "(0,87,m-0.66m)x10:2:3=0", the notation "(0,87,m-0.66m)" is not a valid mathematical expression. It seems to contain three values, separated by commas, but it's not clear what they represent. Additionally, the notation "x10:2:3=0" is also unclear - it's possible that it's meant to represent multiplication by some factor, but the meaning of the "10:2:3" part is unclear.

Similarly, in the second expression, "10x(1,37k-0.12k):5:8=0", the notation "10x" is unclear - it's possible that it's meant to represent multiplication by 10, but it's not clear what is being multiplied. The expression "(1,37k-0.12k):5:8" is also unclear - it's possible that it's meant to represent some kind of division, but the meaning of the "5:8" part is unclear.

If you can provide more information or clarification about the expressions, I may be able to help you solve them.
