Yang tau tolong jawab ya operasi bilangan penting 1. 129,15 m + 13,4 m 2. 4,76 × 10^3 m - 2354 m 3. 14,4 m × 7,8 m × 5 m
rahmy
1. 129,15 m + 13,4 m = 1291,5 x 10^-1 m + 134 x 10^-1 m = 1425,5 x 10^-1 m = 1,4255 x 10^2 m 2. 4,76 x 10^3 m - 2354 m = 4,76 x 10^3 m - 2,354 x 10^3 = 2,406 x 10^3 m 3. 14,4 m x 7,8 m x 5m = 561,6 m = 5,616 x 10^2 m
= 1,4255 x 10^2 m
2. 4,76 x 10^3 m - 2354 m = 4,76 x 10^3 m - 2,354 x 10^3 = 2,406 x 10^3 m
3. 14,4 m x 7,8 m x 5m = 561,6 m = 5,616 x 10^2 m
