Simplfying expression to get $b-a$

$$frac{3}{4}(b-a)left( frac{2a}{3}+frac{b}{3} right)^0 + left( frac{b-a}{4} right)b^0 = b-a$$
I know that $$left( frac{2a}{3}+frac{b}{3} right)^0 = 1$$
and $$left( frac{b-a}{4} right)b^0=frac{b-a}{4}$$
but then how do I simplify the rest to get the solution which Is $b-a$?

Let $t=b-a$. Then don't you simply have $$frac 34 t+ frac 14 t=t$$ which is blatantly obvious?

$$frac{3}{4}(b-a)left( frac{2a}{3}+frac{b}{3} right)^0 + left( frac{b-a}{4} right)b^0 = b-a$$
$$frac{3}{4}(b-a)cdot1+left( frac{b-a}{4} right)cdot1=b-a$$
$$dfrac{3b-3a}{4}+dfrac{b-a}{4}=b-a$$
$$dfrac{4b-4a}{4}=b-a$$
$$b-a=b-a$$

The equation becomes $$
frac{3}{4}(b-a) + left( frac{b-a}{4} right) = b-a \
frac{3}{4}(b-a) + frac{1}{4}(b-a) = b-a \
b-a=b-a
$$
