Find the values for c and d
that would make the following
equation true,
(cy^2) (4y^d)=-20y^3

c=-5

d=1

Step-by-step explanation:

I'm going to reorder the left-hand side.  Multiplication is commutative.

Since the bases are the same in and the operation is multiplication, I'm going to add the exponents giving me:

So this implies we have two equations to solve:

and

So the first equation can be solved by dividing both sides by 4 giving you .

The second equation can be solved by subtracting 2 on both sides giving you .

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
