Question

4) Determine as potências. (1,0)
a) (a3 . b2. C )3 =
b) (- 8 x y3) 2 =
c)
d) ( - 9 x y2 y3 )3

Answer 1

Explicação passo-a-passo:

A)

${a}^{3 \times 3 } \times {b}^{2 \times 3} \times {c}^{3} \\ {a}^{9} \times {b}^{6} \times {c}^{3}$

B)

$- {8}^{2} {x}^{2} \times {y}^{3 \times 2} \\ 64 {x}^{2} \times {y}^{6}$

C)

D)

${ - 9}^{3} {x}^{3} {y}^{(2 + 3) \times 3} \\ - 724 {x}^{3} {y}^{15}$
