What is the power of a variable?

The power of a variable refers to the exponent of the variable and the highest power of a variable is the degree to which the variable is being raised. From the information given, the highest power of the variable is a polynomial.

Given that:

[tex]\mathbf{= 2.150 \times 10^2 \ cm + 7.34 \times 10^2 \ cm - 3.2 \times 10^2 \ cm }[/tex]

So, since the exponents are in the same power we are going to add them all together multiplied by their exponent.

i.e.

[tex]\mathbf{= (2.150 + 7.34 - 3.2) \times 10^2\ cm }[/tex]

[tex]\mathbf{= 6.29 \times 10^2\ cm }[/tex]
