Giúp mik với ak

Answer 1

\(-\sqrt{25}+\sqrt{\frac{9}{4}}\\ =-5+\frac{3}{2}\\ =\frac{-10}{2}+\frac{3}{2}\\ =\frac{-7}{2}\)

Answer 2

\(=-\sqrt{5^2}+\frac{\sqrt{3^2}}{\sqrt{2^2}}\)

\(=-5+\frac{3}{2}\)

\(=-5+1,5\)

\(=-3,5\)

Answer 3

\(-\sqrt{25}+\sqrt{\frac{9}{4}}\)

= \(-5+\frac{3}{2}\)

= \(\frac{-10}{2}+\frac{3}{2}\)

= \(-\frac{7}{2}\)

Answer 4

\(-\sqrt{25}+\sqrt{\frac{9}{4}}=-5+\frac{3}{2}=\frac{-10}{2}+\frac{3}{2}=\frac{-7}{2}\)

Answer 5

\(-\sqrt{25}\) + \(\sqrt{\dfrac{9}{4}}\)

= (-5) + \(\dfrac{3}{2}\)

= \(\dfrac{-10}{2}\) + \(\dfrac{3}{2}\)

= \(\dfrac{-7}{2}\)

Answer 6

\(-\sqrt{25}+\sqrt{\dfrac{9}{4}}\)

\(=\left(-5\right)+\dfrac{3}{2}\)

\(=\dfrac{-10}{2}+\dfrac{3}{2}\)

\(=\dfrac{-7}{2}\)
