Question

[(35:7+21:7)×7+(4+9:3+27)]×7=630????urgent va rog​

Answer 1

[(5+3)×7+(4+3+27)]×7=630

(8×7+34)×7=630

(56+34)×7=630

90×7=630

630=630 deci da

Answer 2

Adevărat:

$\left[\left(35\div \:7+21\div \:7\right)\times \:7+\left(4+9\div \:3+27\right)\right]\times \:7$

$=8\times \:7+\left(4+9\div \:3+27\right) =8\times \:7+34=56+34 =90$

$=90\times \:7 =630$

Sper că te-am ajutat!

Succes!
