Question

ok i have to use the product property to simplify the expression

√ = Square root

1. 1/4 * √80

how do i simplify this and also

2. 2/3 * √98

and

3. 10 * √ 5/36

4. 21 * √ 48/49

thanks if u can help

Answer 1

1. 2.2360

2. 6.5996

3. 3.7267

4. 20.784

I really don&#039;t know I&#039;m sorry

but I tried Lol.

Answer 2

1. Take the 80 and make it so it&#039;s down to the lowest # it can be and still be in a square root thing...

2. same thing as one

i.e √32 = √16x2= 4√2

3. You can&#039;t have fractions in a square root

4. Same as three

Answer 3

Don&#039;t know

Answer 4

lemme answer number 1 for u

1/4 * √80

= 1/4 √4*20

= 1/4 2√20

1/2 *√20

then

1/2 * √4*5

1/2 2 √5

final answer = √5

or if you want the shortcut!

1/4 * √80

= 1/4 * √16*5

= 1/4 4 √5

final answer = √5

for the fractions

i&#039;m not sure but i think u have to make it so that the whole numbers are in √ mode as well. then multipy and simplify

amidoingitrite?

Answer 5

Well if you are simplifyting work with the square root.

1. Take 80. If 20 * 4 equals 80 then you can substitute that under the square root sign. So now that you have 20 * 4 you can pull a 2 out of the square root because the square root of 4 is 2. Now you have 2 and under the square root 20. 5 * 4 is 20, you are doing the same thing so now you can pull the other 2 out and have 4 and the square root of 5. Add this to the 1/4 you already have. 4 and 1/4 and the square root of 5.

Try and take the problem solving I did above and apply it to the other problems. I hope this helps!! Good Luck!! :D
