Simplify 7w x 9x x 10y?

To simplify the expression ( 7w \times 9x \times 10y ), you can multiply the coefficients (numerical parts) and combine the variables.

1. First, multiply the coefficients: ( 7 \times 9 \times 10 = 630 )

2. Then, combine the variables: ( w \times x \times y = wxy )

Putting it all together, you get: [ 630wxy ]

So, the simplified expression is ( 630wxy ).
