Apakah akar kuadrat 98 minus, punca kuad 24 ditambah punca kuasa dua 32?

Jawapan:

# 11 * sqrt (2) -2 * sqrt (6) #

Penjelasan:

#sqrt (98) = sqrt (2 * 49) = sqrt (2) * 7 #

#sqrt (24) = sqrt (6 * 4) = 2sqrt (6) #

#sqrt (32) = sqrt (2 * 16) = 4 * sqrt (2) #

Jawapan:

# 11sqrt (2) -2sqrt (6) #

Penjelasan:

#sqrt (98) = sqrt (2xx7xx7) = 7sqrt (2) #

#sqrt (24) = sqrt (2xx2xx2xx3) = 2sqrt (6) #

#sqrt (32) = sqrt (2xx2xx2xx2xx2) = 4sqrt (2) #

# 7sqrt (2) -2sqrt (6) + 4sqrt (2) = 11sqrt (2) -2sqrt (6) #

Jawapan:

# 11sqrt2-2sqrt6 #

Penjelasan:

# "menggunakan" undang-undang radikal "warna (biru)" # "

# • warna (putih) (x) sqrtaxxsqrtbhArrsqrt (ab) #

# "memudahkan setiap pemberian radikal" #

# sqrt98 = sqrt (49xx2) = sqrt49xxsqrt2 = 7sqrt2 #

# sqrt24 = sqrt (4xx6) = sqrt4xxsqrt6 = 2sqrt6 #

# sqrt32 = sqrt (16xx2) = sqrt16xxsqrt2 = 4sqrt2 #

# rArrsqrt98-sqrt24 + sqrt32 #

# = warna (biru) (7sqrt2) -2sqrt6color (biru) (+ 4sqrt2) #

# = 11sqrt2-2sqrt6 #
