Question

50 POINTS! I'm completely lost. How do you find the approximation of this?

5.0/√61

Answer 1

Multiply the numerator and denominator by the conjugate
5/61 (square root sign) 61
= (Decimal: 0.640184)

Hopefully this is what you mean...

Answer 2

`\\ \sf\longmapsto (5.0)/(√(61))`

`\\ \sf\longmapsto (5.0)/(7.3)`

`\\ \sf\longmapsto 0.6849`

`\\ \sf\longmapsto 0.685`

`\\ \sf\longmapsto 0.68`

`\\ \sf\longmapsto 0.7`
