Answer 1

Resposta:

a)

${5}^{13}$

b)

${3}^{ - 5}$

c)

${2}^{6}$

d)

$y^{14}$

e)

$\frac{ {3}^{12} }{2 ^{12} }$

= 3/2

Answer 2

Resposta:

a) $5^2.5^7.5^4=5^2^+^7^+^4=5^1^3$

b) $\dfrac{3^1^2}{3^1^7} =3^1^2^-^1^7=3^-^5$

c) $(2^2)^3=2^2^.^3=2^6$

d) $y^2.y^8.y^4=y^2^+^8^+^4=y^1^4$

e) $\dfrac{3^5.3^7}{2^1.2^1^1} =\dfrac{3^5^+^7}{2^1^1^+^1} =\dfrac{3^1^2}{2^1^2} =\dfrac{3}{2}$
