# how to find the simplest radical form

Question:How to put the following in simplest radical form? 1. ( 2 - 3) ( 2 + 3) 2. ( 3 - 5) ( 3 - 5) Thanks.

Answers:2-9 = -7 3 -2Sq rt 15 +5 = 8- sqrt 15

Question:4 algebra problems, express in simplest radical form? please show how you got the answers (note means the square root Symbol seeing as that's as close as i can get to it 1. 2 + 2/49 2. 3 2 + 50 3. ( 2-3)( 2+3) 4. ( 3 - 5)( 3- 5)

Answers:1. 2 + (2/49) = 2 + ( 2 / 49) = 2 + ( 2 / 7) = (7 2 / 7) + ( 2 / 7) = (8 2 / 7) 2. 3 2 + 50 3 2 + 50 = 3 2 + (25 * 2) = 3 2 + 5 2 = 8 2 3. ( 2-3)( 2+3) ( 2-3)( 2+3) = ( 2)^2 - (3)^2 = 2 - 9 = -7 4. ( 3 - 5)( 3- 5) ( 3 - 5)( 3- 5) = ( 3)^2 - 2( 3)( 5) + ( 5)^2 = 3 - 2 15 + 5 = 8 - 2 15

Question:5 algebra problems, express in simplest radical form? please show how you got the answers (note means the square root Symbol seeing as that's as close as i can get to it 1.3 13/3 2. m m^2 3. 3 2 + 5 2 4. 3 8 + 2 16 5. m^2/n^3

Answers:1. 3 (13/3) = 3 (4*1/3) = 6 (1/3) 2. (m) (m^2) = m (m) 3. 3 (2) + 5 (2) = 8 (2) 4. 3 (8) + 2 (16) = 3 (4*2) + 2 (16) = 6 (2) + 8 5. (m^2/n^3) = (m^2*1/n^3) = m (1/n^3)

Question:please explain to me how to find the simplest form of: a - 64 (a - 8) (a - 7)

Answers:a - 64= (a-8)(a+8) so you can cancel one of the (a-8) on top with an (a-8) on bottom. This leaves you with (a+8) / (a-7)
