1) √(9/16) + куб√(-2 10/27) + четв.степ.√81 = 3/4 + куб√(-64/27) + 3 = 3/4 - 4/3 + 3 = 9/12 - 16/12 + 3 = 3 - 7/12 = 2ц 5/12
2) √0.49 - куб√(-15 5/8) + пят.степ.√32 = 0.7 - куб√(-125/8) + 2 = 2.7 - (-5/2) = 2.7 + 5/2 = 2.7+2.5=5.2
3) √(16/25) + куб√(-1 61/64) + шест.степ.√(64) = 4/5 + куб.√(-125/64) + 2 = 0.8 - 5/4 + 2 = 2.8-1.25=1.55
4) √1.21 + куб√(-4 12/125) + четв.степ.√625 = 1.1 + куб√(-512/125) + 5 = 6.1 - 8/5= 6.1 - 1.6 = 4.5
