1.Simplify:

(y^4) (y^3)

When multiplying/dividing, exponents are added/subtracted respectively.

To simplify the expression (y^4) * (y^3), you need to use the exponent property that states: when you multiply two terms with the same base, you need to add their exponents.

In this case, the base is "y," and we have (y^4) multiplied by (y^3).

To simplify, add the exponents together:

y^4 * y^3 = y^(4+3)

Simplifying further:

y^(4+3) = y^7

So, the simplified expression is y^7.
