Question

What is the following product?

StartRoot 10 EndRoot times StartRoot 10 EndRoot
10
10 StartRoot 10 EndRoot
100
2 StartRoot 10 EndRoot

Answer 1

2,000,000

Explanation:

First of all, I think that you are asking:

`√(10)*√(10)*10*10√(10)*100*2√(10)`=?

So, because multiplication is commutative, we are allowed to group together what we know and what we will deal with later:

`√(10)*√(10)*10*10√(10)*100*2√(10)` can be rewritten as

`(10*10*100*2)*√(10)* √(10)*√(10)*√(10)`

10*10*100*2=20,000

`20,000(√(10)*√(10)*√(10)*√(10))`

So, what we do know is that when we take the square root of a number and multiply it by itself (or "square" it) we will get back the number that we started with.

So:

`√(10)*√(10) =10`

We can rewrite what we had up top as:

`20,000((√(10))*(√(10)))*((√(10))*(√(10)))`

`20,000(10)(10)`

`20,000(100)`

`20,000(100)=2,000,000`
