Anyone know the answer? much appreciate the

and

Step-by-step explanation:

we have

Solve for x

That means-----> isolate the variable x

squared both sides

Take the square root both sides

therefore

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
