(4x⁵)²=
(7y²)•(8y⁷)=
(9z¹³):(3z²)=

quero a conta de todas elas!​

Answer 1

Resposta:

OLÁ

A)

$(4 {x}^{5} ) ^{2} \\ 4 ^{2} \times (x ^{5} ) ^{2} \\ 16 \times ( {x}^{5} ) ^{2} \\ 16 \times x^{10} \\ \blue{16 ^{10} }$

B)

$(7y ^{2} ) \times (8y ^{7} ) \\ (7 \times 8) \times (y ^{2} \times {y}^{7} ) \\ 56 \times (y ^{2 + 7} ) \\ 56 \times y ^{9} \\ \blue{56y ^{9}}$

C)

$(9z ^{13} ) \div (3z ^{2}) \\ (9 \div 3) \times (z ^{13} \div z ^{2} ) \\ 3 \times (z ^{13 - 2} ) \\ 3 \times z ^{11} \\ \blue{3 ^{11} }$
