Online "^" is used to indicate an exponent, e.g., x^2 = x squared.
Assuming that you mean (y^4)(y^3) with the numerals as exponents. When multiplying with the same base, the exponents are added.
(y^4)(y^3) = y^7
(y4)(y3)
y1
y2
y12
y43
I think it is y12

Since y^7 that is not a choice, I'll assume you meant
y^4 / y^3 = y^1
y^4 / y^3 = y^1
Either it is
y^1
or
y^7.
y^1
or
y^7.
