Step-by-step explanation:
y9 divided by y3
[tex]\frac{y^9}{y^3}[/tex]
When the base of the exponent are same and they are in division then we subtract the exponents.
[tex]\frac{y^9}{y^3}=y^{9-3}=y^6[/tex]
2^3 divided by 5^2
[tex]\frac{2^3}{5^2}[/tex]
The exponents of base are not same, so we cannot subtract the exponents
[tex]2^3=8[/tex] , [tex]5^2= 25[/tex]
[tex]\frac{8}{25}[/tex] = 0.32 is a decimal number
