Question

3√27 - 5.5√243 + 7.3√125 + 3√64 ?​

Answer 1

Step-by-step explanation:$\sqrt[3]{3*3*3} - 5.\sqrt[5]{3*3*3*3*3} - 7.\sqrt[3]{5*5*5} + \sqrt[3]{4*4*4}$

as mentioned find the root as respected numbers  for eg $\sqrt[5]{2}$ then you can eliminate root  only if 2*2*2*2*2 is inside

As mentioned above we will find root of all numbers

3 - 5.3 - 7.5 + 4

If point means multiply then multiply and then add but if it means normal point then calculate like below

3 - 12.8 + 4

3 - 8.8

- 5.8 Answer

However i think point means multiply so follow this

3 - 5.3 - 7.5 + 4

3 - 15 - 35 + 4

3 - 50 + 4

3 - 46

- 43
