#1

  • √0.084
  • √(841×0.0001)

√ab=√a√b

  • √841√0.0001
  • √(29)²√(0.01)²
  • 29(0.01)
  • 0.29

Let they be x and x+2

  • x²+(x²+4x+4)=130
  • 2x²+4x=126
  • x²+2x=63
  • (x+9)(x-7)=0
  • x+9=0 and x-7=0
  • x=-9,7

It's given that two consecutive square nos

A square no must be positive integer so -9 can't be that

  • x=7 only

The next odd no=7+2=9

The numbers are 7 and 9
