Answer:

[tex]\frac{ - 5}{54} + \frac{5 \times 6}{9 \times 6} = \frac{ - 5 + 30}{54} = \frac{25}{54} [/tex]

[tex] \frac{15}{4} \div \frac{3}{8} = \frac{15}{4} \times \frac{8}{3} = 10[/tex]

[tex]10 \times \frac{25}{54} = \frac{250}{54} = 4 \times \frac{17}{27} [/tex]

b )

[tex]4 \times \frac{17}{27} = \frac{125}{27} =[/tex]

cube root =

[tex] \frac{5}{3} [/tex]

c ) square root

[tex] \frac{125}{27} = \frac{ \sqrt{25 \times 5} }{ \sqrt{3 \times 9} } = \frac{5 \sqrt{5} }{3 \sqrt{3} } [/tex]
