\(\sqrt{64}+3.\sqrt{\left(\frac{1}{2}\right)^0}-\frac{\sqrt{16}}{4}+\left(\sqrt{\left(-4\right)^2:\frac{1}{2}}\right).8\)
= \(8+3.1-\frac{4}{4}+\left(\sqrt{16:\frac{1}{2}}\right).8\)
=\(8+3-1+\left(\sqrt{16.2}\right).8\)
=\(8+3-1+\left(\sqrt{32}\right).8\)
=\(11-1+\left(\sqrt{32}\right).8\)
= \(10+5,65685424949.8\)
= \(10+45,2548339959\)
=\(55,2548339959\)
Mình ko biết là có đúng không í
vì mình thấy đề bài có gì sai ý!!!
\(\sqrt{64}+3\sqrt{\left(\frac{1}{2}\right)^0}-\frac{\sqrt{16}}{4}+\left(\sqrt{\left(-4\right)^2}:\frac{1}{2}\right).8\)
\(=\sqrt{8^2}+3\sqrt{1}-\frac{\sqrt{4^2}}{4}+\left(\sqrt{16}:\frac{1}{2}\right).8\)
\(=8+3-\frac{4}{4}+\left(\sqrt{4^2}:\frac{1}{2}\right).8\)
\(=11-1+\left(4.2\right).8\)
\(=10+8.8=10+64=74\)
cái này bấm máy tính casio hoặc deli.... là ra ngay hoi !!!
\(\sqrt{8}+3.\sqrt{\left(\frac{1}{2}\right)^0}-\frac{\sqrt{16}}{4}+\left(\sqrt{\left(-4\right)^2}:\frac{1}{2}\right).8\)
\(=8+3-\frac{4}{4}+\left(4:\frac{1}{2}\right).8\)
\(=10+8.8\)
\(=74\)
