Idon’t know how to simplify radical expressions

FIrst you want to find the largest perfect square. Next, you want to rewrite the radical number then rewrite the radical number idk how to explain it so i will show you an example:

the square root of 8= the square root of four and the square root of two.

Then simplify:

So it would be 8= 2 square root of 2.

Hope this helps, have a good day. c;

Here are some examples:-

√8 = √(4*2)  Note we picked 4 as a factor because its a perfect square

√(4*2) = √4 *√2

= 2√2

√63 = √(9*7)

= 3√7

correct answer:

i^31 = -i

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it
