Multiplying Radicals and Then Simplifying

👉 Learn how to multiply radicals. A radical is an expression or a number under the root symbol. To multiply radicals with the same root, it is usually easy to evaluate the product by multiplying the numbers or expressions inside the roots retaining the same root, and then simplify the result.
To multiply radicals of different roots. It is usually easier to simplify the radicals first or transform the radicals into exponent form before multiplying them.

Hello Brian, great lecture. It’s 55 years approx since I must have covered this, but it’s gone into the ether , even though I have an engineering degree. So I’m trying to keep my brain active and filling in all the gaps which I suspect hindered me then. From across the pond.

Wait I don’t understand how you got a 3•2 before the arrow

[@ChewyTheCookie]

Lana Del Sirena I know this is late but I believe he factored the 4 so that’s how he got a 2.

[@kirklurkpu4470]

The radical 9 turned to 3 when it got down because the square root of 9 is 3. Square roots are the outcomes of a number when you multiply them to themselves. For example, like this one, 3x3 = 9, therefore 3 is the square root of 9. One more example is square root of 16, is 4, because 4x4 = 16.

[@tristanbailey8865]

[@samellis7358]

[@kansasbrown2201]

I have a method where you multiply the insides so 18x14 wich is 252 and then you birthday cake it 3x2 is 6 so six is on the outside and you have a leftover 7 so i got the same answer. I hate on quizes they make you do it a certain way. Thanks for the video by the way it helped me learn the other way to solve :)

[@TheReal_Ari]

Thank you so much for these videos❤❤❤

[@bwzboddah5219]

This is all cool, Brian, but like, how do you multiply a radical by an exponent-ed variable?

[@brianmclogan]

you can convert the radical to a rational power and then use the properties of exponents as long as they have the same bases

How did this 4 minute video teach me more than 3 9 minute videos could?

[@lchazea.m.9192]

I have questions Pls answer :) When you add radicals can you ADD both radicals even if both radicals are not the same number? And is it only MULTIPLYING radicals you can be allowed to multiply two different radicals?

[@brianmclogan]

try it sqrt(4) +sqrt(9) =/ sqrt(13) if you simplify you see that sqrt(4)+sqrt(9)=2+3=5 =/ sqrt(13) try it with multiplication/division and you see it works, not addition/subtraction

[@lchazea.m.9192]

I tried this method with the following example: √98 * √32 and I got 12√2. But my math teacher said that answer was 56. I'm sort of confused..

[@jasrajsingh3532]

Zulayho Omonova well if you do it the long way you can multiply 98x32 then you will get 3136 and then if you just put it in your calculator and ask for square root you should get 56

[@jasrajsingh3532]

Srry if it was a bit late lol

[@jackdavis8596]

√98 can be simplified to √7x √7x 2 x or 7√2. Then simplify √32 to √16 √2 or 4√2. Multiply them together: 7x4=28 and √2 x √2=2, so it's 28x2=56. Maybe you added 7 and 4?

[@TheRazz1717]

56 is correct. 98 = sr 2 × sr 49 and 32 = sr 2 x sr 16. Simply sq 2 x 7 and sq 2 x 4. Multiply like numbers 7 x 4 = 28 and sq 2 times sq 2 = 2. Simply 2 x 28 = 56, easy.

[@bigrichard5735]

i thought u were johnny sins for a sec

could have simplified rad 14 in to rad 2 and rad 7 , first instead of making it 28 and change it back

[@reinhardtristaneugen9113]

well I got 15,87 as I did multiply the both numbers at first - 14 times 18 result in 252 and then I extracted the root of it... ...of course you can extract the root at first as well and then multiply, what makes for the same result.
