you are going far beyond the calculation. No need to calculate as much as you do. Just follow the the second factor , it results zero and when zero is multiply by anything answer always come zero.

Answer:
Required numeric value of ( 5√3 - 2√2 )( - 3√3 + 3√3 ) is 0.]
Step-by-step explanation:
We have to multiply ( 5√3 - 2√2 )( - 3√3 + 3√3 )
There are two methods for the solution : -
Method 1 -
= > ( 5√3 - 2√2 )( - 3√3 + 3√3 )
= > ( 5√3 - 2√2 )( 0 )
We know, result becomes 0 when we divide or multiply any number by 0.
= > 0
Method 2 -
= > ( 5√3 - 2√2 )( - 3√3 + 3√3 )
= > 5√3( - 3√3 + 3√3 ) - 2√2( - 3√3 + 3√3 )
= > - ( 5 x 3 x √3 x√3 ) + ( 5 x 3 x √3 x √3 ) + ( 2 x 3 x √2 x √3 ) - ( 2 x 3 x √2 x √3 )
= > - ( 15 x 3 ) + ( 15 x 3 ) + ( 6 x √6 ) - ( 6 x √6 )
= > - 45 + 45 + 6√6 - 6√6
= > 0
Hence the required numeric value of ( 5√3 - 2√2 )( - 3√3 + 3√3 ) is 0.
