Question

Simplify (5√3+3)(5√3-3)​

Answer 1

$\huge\bold{\underline{\underline{Answer}}}$

$\implies(5 \sqrt{3} + 3)(5 \sqrt{3} - 3)$

$\implies( {5 \sqrt{3}) }^{2} - ( {3})^{2}$

$\implies75 - 9$

$\implies66$

Answer 2

Answer:

66

Step-by-step explanation:

(5_/3+3)(5_/3-3)

(a+b)(a-b)=a^2-b^2

here, a= 5_/3 b= 3

(5_/3)^2 - (3)^2

= (25 × 3) - 9

= 75-9

=66
