Question

Tính:

a)\(\frac{2}{3}\)+\(\sqrt{2.25}\).\(\sqrt{1\frac{11}{25}}\)-\(\frac{1}{5}\)

b)\(\left(\frac{-1}{3}\right)^2\).\(\frac{27}{2}\)-\(\frac{5}{5^2}\):\(\sqrt{\frac{25}{36}}\)

c)\(\frac{1}{2}.\sqrt{1,24}.\sqrt{1\frac{9}{16}}+\frac{1}{4}\)

Mí bạn làm nhớ ghi rõ cách nhé. Ghi rõ mik cho 3 tick lun. Ghi kết quả không tick đâu nghen.

Answer 1

a)= \(\frac{2}{3}+\frac{3}{2}.\frac{6}{5}-\frac{1}{5}\)

=\(\frac{13}{6}.1\)=\(\frac{13}{6}\)

b)= \(\frac{1}{9}.\frac{27}{2}-\frac{1}{5}:\frac{5}{6}\)

=\(\frac{3}{2}-\frac{6}{25}=\frac{63}{50}\)
