(sin30º)﹣²﹢1﹣|3-√18|﹢8³×(-0.125)﹣³ 等于多少啊
(sin30º)﹣²﹢1﹣|3-√18|﹢8³×(-0.125)﹣³ 等于多少啊
(sin30º)﹣²﹢1﹣|3-√18|﹢8³×(-0.125)﹣³ 等于多少啊
(sin30º)^(-2)﹢1﹣|3-√18|﹢8³×(-0.125)^(-3)=(1/2)^(-2)+1-3√2+3+8³×(-8)^3
=4+1-3√2+3-8^6
=8-3√2-8^6
如果不懂,请Hi我,祝学习愉快!
(sin30º)﹣²﹢1﹣|3-√18|﹢8³×(-0.125)﹣³
=4+1-(3√2-3)-8³×8³
=5+3-3√2-262144
=-262136-√3
=4+1-3+3倍根号3+512-512
=2+3倍根号3
