आप (4 + sqrt50) क सरल क स बन त ह - (3-sqrt (8))?

उत तर:

# = 1 + 7sqrt2 #

स पष ट करण:

# Sqrt50 = 5sqrt2 # तथ # Sqrt8 = 2sqrt2 #

सम करण बन ज त ह # (4 + 5sqrt2) - (3-2sqrt2) #

# = 4 + 5sqrt2-3 + 2sqrt2 #

# = 1 + 7sqrt2 #

उत तर:

# (4 + sqrt50) - (3-sqrt8) = 1 + 7sqrt2 #

स पष ट करण:

# (4 + sqrt50) - (3-sqrt8) #

# Sqrt50 = sqrt (25xx2) = sqrt25xxsqrt2 = 5sqrt2 #

# Sqrt8 = sqrt (4xx2) = sqrt4xxsqrt2 = 2sqrt2 #

# (4 + sqrt50) - (3-sqrt8) = (4 + 5sqrt2) - (3-2sqrt2) #

# = 4 + 5sqrt2-3 + 2sqrt2 #

# = (4-3) + (5sqrt2 + 2sqrt2) #

# = 1 + 7sqrt2 #

# (4 + sqrt50) - (3-sqrt8) = 1 + 7sqrt2 #
