Question

PLEASE HELP!!!!!!!!!!!!!

Find the sum.

(5+ √12) + (-2 √3)=?

Answer 1

Given equation : ( 5 + √12 ) + ( - 2√3 )

Step 1: Opening brackets.

⇒ 5 + √12 - 2√3

Now, factorizing 12.

12 = 2 x 2 x 3

    = 2² x 3

⇒ 5 + √( 2² x 3 ) - 2√3

⇒ 5 + ( √2² x √3 ) - 2√3

⇒ 5 + $2^{2 \times \frac{1}{2} }$-2√3

⇒ 5 + 2√3 - 2√3

⇒ 5

Therefore the sum of ( 5 + √12 ) and ( - 2√3 ) is 5.
