(y4)(y3)
y1
y2
y12
y43
I think it is y12
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
Since y^7 that is not a choice, I'll assume you meant
y^4 / y^3 = y^1
Either it is
y^1
or
y^7.
To determine the value of the expression (y4)(y3), you need to multiply the exponents and combine the variables.
In this case, the exponent of y is 4 in the first term and 3 in the second term. When we multiply these exponents, we get 4 + 3 = 7.
Now, the base of the variables is also y. So, when we combine the variables, we get y^7.
Therefore, the expression (y4)(y3) simplifies to y^7.
Now, let's consider the options you provided: y1, y2, y12, and y43.
The correct answer is y^7, not y12 or any of the other options.
