numarul natural a da restul 1 la impartirea prin 3 ce rest da numarul natural b la impartirea prin 3 daca numarul a si b da restul 2 la inpartirea prin 3 repede va rog dau coroana

8, nu prea înțeleg ce spui. dar se pare că dacă doriți să împărțiți la 3 și să primiți un memento de 2, trebuie să faceți 8

Step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
