Explicație pas cu pas:

Buna !!

[tex]49 + 36 \times 3 - 64 \div 8 \div 4 = 49 + 108 - 8 \div 4 = 49 + 108 - 2 = 157 - 2 = \red {155} [/tex]

[tex]4781 - (407 + 63 \div 9) \times 3 + 56 \div 7 \div 4 = 4781 - (407 + 7) \times 3 + 8 \div 4 = 4781 - 414 \times 3 + 2 = 4781 - 1242 + 2 = 3539 + 2 = \red{3541} [/tex]

Succes !!;)
