Answer 2

Step-by-step explanation:

(✓90+✓80) × (✓2-1)

=(✓180-✓90+✓160-✓80)⁴ also adding power 4

=(6✓5 -3✓10+4✓10-4✓5)⁴

=(2✓5+✓10)⁴ ( here you can directly calculate or have fun and proceed)

=[(2✓5)²+(✓10)²+2×2✓5×✓10]²

=[ 20+10+4✓50]²

=[30+4×5✓2]²

=[ 30+ 20✓2]²

= 30²+(20✓2)²+2×30×20✓2

= 900+800+1200✓2

=1700+1200✓2

=1700+1697= 3397
