Question

Simplifiquei a potencia por favor precisog para hoje

Answer 1

$\frac{(y^4.y^{-6}) \div y^{-8}}{y^{-5}}=\frac{y^{-2} \div y^{-8}}{y^{-5}}=\frac{y^6}{y^{-5}}=y^{11}$


$\frac{3^{2x+1}*3^{x-2}}{3^{2x+3}}=3^{2x+1+x-2-(2x+3)}=3^{x-4}$

$\frac{(3.5)^3.3^5}{3^{-3}.5^4}=\frac{3^3.5^3.3^5}{3^{-3}.5^4}=\frac{3^8.5^3}{3^{-3}.5^4}=3^{11}.5^{-1}=\frac{3^{11}}{5}$
