Simplify the exponent in 6y^6 × 3y^3 × 5y^2

It's 90y^11.

Step-by-step explanation:

All you have to do is multiply 6y x 3y x 5y and get 90y

and you just add the exponents 6 + 3 + 2 and get 11

c).  (1, 0).

Step-by-step explanation:

A general point on a graph is written as (x, y).

If a point is located on the x-axis the y coordinate is 0.

So it is (1, 0).
