Question

Efectuati calculele:
c) [-1•(+2)•(-3)]^4:36=
d) [-2•(-3)•(-5)]^3:(-900)=
Plsssss va roggggg!!!!

Answer 1

Răspuns:

c) [-1×(+2)×(-3)]⁴:36=

=[1×(+2)×(-3)]⁴÷36=

=[2×(-3)]⁴:36=

=

$\frac{(2x( - 3)) {}^{4} }{36}$

$\frac{16 \times81 }{36}$

$\frac{4 \times 81}{9}$

=4×9=

=36

d) -[2×(-3)×(-5)]³÷(-900)=

=[2×(-3)×(-5)]³÷900=

$\frac{(2 \times ( - 3) \times ( - 5)) {}^{3} }{900}$

$\frac{8 \times ( - 27) \times ( - 125)}{900}$

$\frac{8 \times 27 \times 125}{900}$

$\frac{2 \times 27 \times 125}{225}$

$\frac{2 \times 3 \times 125}{25}$

=2×3×5=

=30
