Question

se alguém souber me ajudem por ​favor

Answer 1

Explicação passo a passo:

(3)---

a) = $3^{a+b}=3^{2+8}=3^{10}$

b) = $\frac{2^{10}*2^{10}}{2^{10}} =2^{10}$

c) = $3^{a*b}=3^{2*3}=3^{6}$

d) $= a^m+a^n = 3^{x+2}$

e) $\frac{x}{2^5} = 2^{-5} = \frac{2^x}{2^5} = \frac{2^5 *2^{x-5}}{2^5} = 2^{x-5}$

f) $3^{a*b}=3^{x*3}=3^{3x}$

(4)---

$\sqrt{5} * \sqrt[5]{5^2} = \sqrt{5} * \sqrt[5]{25}\\\sqrt{5} = 5^{\frac{1}{2} } \\reescreva \ \frac{1}{2}\ como\ \frac{5}{10}\\5\frac{1}{2} = \sqrt[10]{5^5} \\\sqrt[5]{25} = 25^{\frac{1}{5} } = 25^{\frac{2}{10} } = \sqrt[10]{25^2} \\\\\sqrt[10]{5^5}*\sqrt[10]{(5^2)^2} = \sqrt[10]{5^5*(5^2)^2} = \sqrt[10]{5^5*5^4}\\\sqrt[10]{5^9}$
