How many zeros will be in the prduct of 7*5000? b) without calculating the answer explain how to use patterns or basic facts to find the number of zeros in the product?

Hello mate!

We have the equation 7*5000 and we want to guess how many zeros this new equation will have.

You know that 7*5 = 35 has not zeros.

Then when you do the product there are no zeros added:

this means that the product still has the initial 3 zeros.

7*5000 = 35000

you can see that it only has 3 zeros:

if for example, we had 6*5000

we know that 6*5 = 30 then this multiple had one zero, and we can guess that the product of 6*5000 will have the 3 zeros in 5000 plus the zero of the product between 5 and 6: this is a total of 4 zeros:

lets check: 6*5000 = 30000

you can see that this product has 4 zeros :).
