• redical

adding or subtracting with redical experience is nothing but algebraic addition or subtraction

let's solve:

$a)7 \sqrt{3} - 2 \sqrt{3} + \sqrt{3} - 3\sqrt{3} \\ 8 \sqrt{3} - 5 \sqrt{3} \\ 3 \sqrt{3}$

$b)5 \sqrt{7} + 4 \sqrt{7} - 8 \sqrt{7} \\ 9 \sqrt{7} - 8 \sqrt{7} \\ \sqrt{7}$

Answer 2

Answer:

• a) 3√3
• b) √7

Step-by-step explanation:

a)

• 7√3 -2√3 + √3 - 3√3 =
• √3(7 - 2 + 1 - 3) =
• √3*3 =
• 3√3

b)

• 5√7 + 4√7 - 8√7 =
• √7(5 + 4 - 8) =
• √7*1 =
• √7
