What is ten times the square root of 45

30√5 or 67.08204

Step-by-step explanation:

You start off with 10√45 and simplify the root by factoring out the perfect square.

Now you have 10√3²*5

Using radical rules you know that the root of a product is equal to the product of the roots of each factor meaning 10√3²*5 can also be written as 10√3² √5

Now we simplify the root by square rooting the square, This gives us 10*3√5

Multiply the 10 and 3 which gives us 30√5 which can also be written as 67.08204
