1. 4√2 × 5√3 2. (3+√2) × (3+√2) 3. √50 + √32 4. √27 + √75

1.
4√2 * 5√3
= 20√6

2.
(3+√2) × (3+√2)
= 3² + 2(3)(√2) + √2²
= 11 + 6√2

3. √50 + √32
= 5√2 + 4√2
= 9√2

4.
√27 + √75
= 3√3 + 5√3
= 8√3

a.4√2.5√3
=4.5√(2.3)
=20√6
2.(3+√2)(3+√2)
=9+3√2+3√2+2
=11+6√2
3.√50+√32
=5√2+4√2
=9√2
4.√27+√75
=3√3+5√3=8√3
