Answer:
Step-by-step explanation:
Lets try to simplify each to check which one is incorrect so it will be NOT true
first one is :
distribute the exponent so :
[tex](3x^2y^5)^3 =3^3x^{2*3}y^{5*3}[/tex]
[tex]27x^6y^{15}[/tex] CORRECT
Second one is :
[tex](1000x^{12}y^{20}z^{-30})^{0} =1[/tex]
CORRECT because anything raised to exponent 0 is 1 .
Last one is :
[tex]4^2 *4^3 = 4^{2+3}\\=4^{6}\\=(4)^{2*3}\\=16^{3}[/tex]
so Last is INCORRECT
