 $3x^0=$  

•  $1$  

•  $0$  

•  $4$  

•  $3$  

Answer explanation

The exponent of zero is only applied to the x, not the 3. so  $3x^0$  = 3(1)=3. For the entire problem to = 1, it would need to be written as  $\left(3x\right)^0$  .

 $\left(x^2y^3z\right)^4$  

•  $4x^8y^{12}z^4$  

•  $4x^2y^3z$  

•  $x^8y^{12}z^4$  

•  $x^6y^7z^5$  

Answer explanation

When you are raising a power to a power, you have to multiply the exponents.  Since there isn't a number in front of the x, there shouldn't be a number in front of the x in our answer  because there isn't a number to raise to the fourth power.

Answer explanation

 $2^3=2\times2\times2=8$  it is  not  $2\times3=6$
