Упр.522 ГДЗ Ткачёва 6 класс (Математика)

1) (3,75 · 14 — 15,328) · 5 — 345,52 : 2,8;
2) (4,09 · 8 — 26,9) · 1,3 — 5,922 : 6,3;
3) 2,3^3 · 20,4 + 13,36 : (0,6 + 3,852 : 3,6);
4) 3,4^2 + 355,47 : (22,7 — 6,3 · 3,05).

1) $$\left(3{,}75 \cdot 14 — 15{,}328\right)\cdot 5 — 345{,}52 : 2{,}8$$

$$3{,}75 \cdot 14 = 52{,}5$$

$$52{,}5 — 15{,}328 = 37{,}172$$

$$37{,}172 \cdot 5 = 185{,}86$$

$$345{,}52 : 2{,}8 = 123{,}4$$

$$185{,}86 — 123{,}4 = 62{,}46$$

2) $$\left(4{,}09 \cdot 8 — 26{,}9\right)\cdot 1{,}3 — 5{,}922 : 6{,}3$$

$$4{,}09 \cdot 8 = 32{,}72$$

$$32{,}72 — 26{,}9 = 5{,}82$$

$$5{,}82 \cdot 1{,}3 = 7{,}566$$

$$5{,}922 : 6{,}3 = 0{,}94$$

$$7{,}566 — 0{,}94 = 6{,}626$$

3) $$2{,}3^3 \cdot 20{,}4 + 13{,}36 : \left(0{,}6 + 3{,}852 : 3{,}6\right)$$

$$2{,}3^3 = 12{,}167$$

$$12{,}167 \cdot 20{,}4 = 248{,}2068$$

$$3{,}852 : 3{,}6 = 1{,}07$$

$$0{,}6 + 1{,}07 = 1{,}67$$

$$13{,}36 : 1{,}67 = 8$$

$$248{,}2068 + 8 = 256{,}2068$$

4) $$3{,}4^2 + 355{,}47 : \left(22{,}7 — 6{,}3 \cdot 3{,}05\right)$$

$$3{,}4^2 = 11{,}56$$

$$6{,}3 \cdot 3{,}05 = 19{,}215$$

$$22{,}7 — 19{,}215 = 3{,}485$$

$$355{,}47 : 3{,}485 = 102$$

$$11{,}56 + 102 = 113{,}56$$

Ответ

1) $$62{,}46$$; 2) $$6{,}626$$; 3) $$256{,}2068$$; 4) $$113{,}56$$.
