Use the properties of radicals to simplify the expression. 6√4⋅8√4
= 4^ (7/24)
6√4⋅8√4=96sqrt(4)
6√4⋅8√4 = 6*2*8*2 = 192
IF you meant the 6th root of 4 times the 8th root of 4:
4^(1/6) x 4^(1/8) = 4^(1/6+1/8) = 4 ^(7/24)
Check:
4^(1/6) = 1.259921
4^(1/8) = 1.189207 Multiplied together = 1.49830
4^(7/24) = 1.49830 Check!
