Question

ayudaaaa es mi tareaaaa

Answer 1

Explicación paso a paso:

a) 72 / 8 + 2 - 4 x 2 / 4 +6

9 + 2 - 4 x 2 / 4 + 6

9 + 2 - 8 / 4 + 6

9 + 2 - 2 + 6

11 - 2 + 6

9 + 6 = 15

b) 5 + 4^2 x 3 x (-2) + 7 - 5^2 x 3

5 + 16 x 3 x (-2) + 7 - 5^2 x 3

5 + 16 x 3 x (-2) + 7 - 25 x 3

5 + 48 x (-2) + 7 - 25 x 3

5 - 96 + 7 - 25 x 3

5 - 96 + 7 - 75

-91 + 7 - 75

-84 - 75= -159

c)

$\frac{ {8}^{2} - {7}^{3} + {5 }^{2} }{ {6}^{3} + {3}^{2} \times ( - 5) } = \frac{64 - 343 + 25}{216 + 9 \times ( - 5)} = \frac{64 - 343 + 25}{216 - 45} = \frac{ - 254}{171}$

d) √81 + 7^2 - 5 x 3^2 - (-6)^3

9 + 7^2 - 5 x 3^2 - (-6)^3

9 + 49 - 5 x 3^2 - (-6)^3

9 + 49 - 5 x 9 - (-6)^3

9 + 49 - 5 x 9 - (-216)

9 + 49 - 45 + 216

58 - 45 + 216

13 + 216= 229

e) (-5+2)^2 + 3^2 x 5^2 x (-2) + 6^3 / 3

(-3)^2 + 3^2 x 5^2 x (-2) + 6^3 / 3

9 + 3^2 x 5^2 x (-2) + 6^3 / 3

9 + 9 x 5^2 x (-2) + 6^3 / 3

9 + 9 x 25 x (-2) + 6^3 / 3

9 + 9 x 25 x (-2) + 216 / 3

9 + 225 x (-2) + 216 / 3

9 - 450 + 216 / 3

9 - 450 + 72

-441 + 72= -369

d)

$\frac{ {4}^{2} + {5}^{3} - 6 \times {3}^{2} - {( - 5)}^{2} }{ {4}^{2} + {3}^{3}( - 2) } = \frac{16 + 125 - 6 \times 9 - 25}{16 + 27( - 2)} = \frac{16 + 125 - 54 - 25}{16 - 54} = \frac{62}{ - 38}$
