Answer:
No
Step-by-step explanation:
Exponents are only added when polynomials are multiplied and only applies to like terms. You add the coefficients of the like terms instead.
For example:
[tex](x^2+3x+6)+(2x^2-4x+1)=(1+2)x^2-(3-4)x+(6+1)=3x^2-x+7[/tex]
Answer:
no
Step-by-step explanation:
The exponents are added when the the same coefficient is multiplied:
[tex]x^2(x^3) = x^5[/tex]
If you think about it:
x^2 = x * x and x^3 = x * x * x
so you get:
(x^2)(x^3) = x * x * x * x * x = x^5
But, when adding x's of the same power, you add a coefficient:
[tex]x^2 + x^2 = 2x^2[/tex], not [tex]x^2 + x^2 = x^4[/tex]
Always remember to only add exponents when the coefficient/variable is multiplied, not added.
And, when an exponent is put to an exponent, multiply them:
[tex](x^3)^3 = x^3^(^3^) = x^9[/tex]
