Question

Calculati A x B daca: A= 2√216 - 6√96 + 5√54 - 3√150 + √600 B= 4√128 - 6√50 + 5√32 - √162 + √98

Answer 1

A=2√216-6√96+5√54-3√150+√600

A=2×6√6-6×4√6+5×3√6-3×5√6+10√6

A=12√6-24√6+15√6-15√6+10√6

A= -2√6

B=4√128-6√50+5√32-√162+√98

B=4×8√2-6×5√2+5×4√2-9√2+7√2

B=32√2-30√2+20√2-9√2+7√2

B=20√2

A×B=

= -2√6×20√2=

= -40×2√3= -80√3
