Question

(−1)² · (−2)² + (−3)³ _ ? (-4)³ +(-5)² =​?

Answer 1

$( - 1) {}^{2} \times ( - 2) {}^{2} + ( - 3) {}^{3} = \\ = 1 \times 4 - 27 = 4 - 27 = - 23$

$( - 4) {}^{3} + ( - 5) {}^{2} = - 64 + 25 = - 39$

Answer 2

Let's solve the expression step by step:

(-1)² = 1² = 1 (-2)² = 2² = 4

Now, let's substitute these values back into the expression:

(−1)² · (−2)² + (−3)³ = 1 · 4 + (-3)³

(-3)³ = -3 × -3 × -3 = -27

Substituting this back into the expression:

1 · 4 + (-27) = 4 - 27 = -23

Therefore, the value of the expression (-1)² · (-2)² + (-3)³ is -23.

Now, let's calculate the second expression:

(-4)³ = -4 × -4 × -4 = -64 (-5)² = 5² = 25

Substituting these values into the expression:

(-4)³ + (-5)² = -64 + 25 = -39

Therefore, the value of the expression (-4)³ + (-5)² is -39.
