Hvordan forenkler du sqrt (9x ^ 2) / sqrt (18y ^ 2)?

Svar:

# X / (sqrt (2) y) #

Forklaring:

#sqrt (9x ^ 2) / sqrt (18y ^ 2) #

# Sqrt9 = 3 #

#sqrt (x ^ 2) = x #

# Sqrt18 = sqrt (9xx2) = 3sqrt2 #

#sqrt (y ^ 2) = y #

Derfor

#sqrt (9x ^ 2) / sqrt (18y ^ 2) = (3x) / (3sqrt (2) y) #=# X / (sqrt (2) y) #

Hvordan forenkler du (sqrt (2) * sqrt (2)) + (sqrt (2) * -sqrt (2)) + (0 * 0)?

= 0 (sqrt2 * sqrt2) + (sqrt2 * -sqrt2) + (0 * 0) = (sqrt4) + (- sqrt4) + (0) = (2) + (- 2) + (0) = 2 - 2 + 0 = 0
