9b2 , if you mean 9b^(2) then the coefficient is the large prefix number, in this case '9'.
Radical 2 is a number, it does not have a coefficient.
2X 2 is the coefficient
8b^2 -9b +1 8b^2 -8b -b +1 8b(b-1) - 1(b-1) (8b-1)(b-1)
2a + 3 - 9b - a - 7 Bring like terms together: = 2a - a - 9b + 3 - 7 Combine like terms: = a - 9b - 4
9b2b is the base.==========9 is the coefficient of the variable term.2 is the exponent.
If the question is, "What is the coefficient of 9b2 ?".......then the answer is 9.
9b2 , if you mean 9b^(2) then the coefficient is the large prefix number, in this case '9'.
(27a)2 = 729a2 (9b)3 = 729b3 So (27a)2 + (9b)3 = 729*(a2 + b3)
2
Radical 2 is a number, it does not have a coefficient.
2X 2 is the coefficient
8b^2 -9b +1 8b^2 -8b -b +1 8b(b-1) - 1(b-1) (8b-1)(b-1)
Since 3b is a factor of 9b, it is automatically the GCF.
8 is the coefficient. A coefficient is the number in front of a variable.
3A + 9B = 3(A + 3B)
