Answer:
21 h^10
Step-by-step explanation:
(7h^3)(3h^7)
Lets multiply
7*3 h^3 h^7
When the bases are the same , we add the exponents (x^a * x^b) = x ^ (a+b)
21 h^(3+7)
21 h^10
Or, is it asking you to subtract the? In that case
5/4 - 3/8 = 7/8
Answer:
We can find the sum of all the coefficients by substituting all the variables in the expansion with one.
a. u=1,v=1
sum==
b.u=1,v=1
sum==1
c.u=1,v=1
sum==-1
d.u=1,v=1
sum==-
e.i=1
sum==
f.i=1
sum==0
g.i=1
sum==
h.i=1
sum==
