Ano ang square root ng 27 plus square square ng 75?

Sagot:

#sqrt (27) + sqrt (75) = 8sqrt (3) #

Paliwanag:

Kung #a, b> = 0 # pagkatapos #sqrt (ab) = sqrt (a) sqrt (b) #

#sqrt (27) + sqrt (75) #

# = sqrt (3 ^ 2 * 3) + sqrt (5 ^ 2 * 3) #

# = sqrt (3 ^ 2) sqrt (3) + sqrt (5 ^ 2) sqrt (3) #

# = 3sqrt (3) + 5sqrt (3) #

# = (3 + 5) sqrt (3) #

# = 8sqrt (3) #
