Question

$(8 { } ^{2} - 15 \times 3 - 2 {}^{3} ) - (9 {}^{3} ) {}^{4} \div (9 {}^{4} ) {}^{2} \div 9 {}^{3} + (2 {}^{2} + 4 {}^{2} - 6) =$
​

Answer 1

Răspuns:

- 56

Explicație pas cu pas:

(8^2 - 15 * 3 - 2^3 ) - (9^3)^4 : (9^4)^2 : 9^3 + (2^2+4^2-6 )

(64-45-8) - 9^12 : 9 ^8 : 9^3 + (4+16-6)

11 - 9^2 + (20-6)

11-81+14

-70 + 14
