Question

plz text the solution in step by step plz plz​

Answer 1

Step-by-step explanation:

Given that:-

(3√5 - 2√3) ×(3√5 + 2√3)

It is in the form of (a+b)(a-b)

Here a=3√5 and b=2√3

we know that

(a+b)(a-b) =a²-b²

(3√5 - 2√3) ×(3√5 + 2√3)

=>(3√5)²-(2√3)²

=>(9×5)-(4×3)

=>45-12

=>33

(3√5 - 2√3) ×(3√5 + 2√3)=33
