-3 raised to the power 0=
son4ous [18]

Given:

The statement is "-3 raised to the power 0".

To find:

The value of the given expression.

Solution:

We know that a raised to the power b can be written as a^b.

Any non zero number raised to the power 0 is always 1. It means,

a^0=1, where a\neq 0.

-3 raised to the power 0 =(-3)^0

                                         =1

Therefore, the value of the given statement is 1.

D. 3 y^{3}x+9 x^{2} y-2 y^{2} -4x

Take each term and find the degree of the term and then put them in order from highest to lowest:
y^{3}x=3+1=4
x^{2} y=2+1=3
y^{2}=2
x=1

Remember a letter without an exponent is assumed to be a 1.

Hope that helps.
