Question

5. Simplify (6+√6)(6-√6).​

Answer 1

Answer:

$\sf{(6+\sqrt6)(6-\sqrt6)}$

$\sf{According \ to \ the \ identity. }$

$\sf{(a+b)(a-b)=a^{2}-b^{2}}$

$\sf{=6^{2}-\sqrt6^{2}}$

$\sf{=36-6}$

$\sf{=30}$

Answer 2

Answer:

(6+√6)(6-√6) = 30

Step-by-step explanation:

Using the formula, a²-b² = (a+b)(a-b)

(6+√6)(6-√6) = 6²- (√6)² = 36 - 6 = 30
