SOLVE THISSSSSSSS question ​

Answer 1

Step-by-step explanation:

We know that 5³ is 125 ie 5×5×5=125.

First,

${125}^{ \frac{ - 1}{3} } = {5}^{3 \times \frac{ - 1}{3} }$

3 and 3 gets cancelled, so it becomes

${5}^{ - 1}$

Now, solving the second bracket

${5}^{ \frac{1}{3} \times 3 }$

3 and 3 gets cancelled and it forms only 5.

Now the one with power 2/3 , denominator 3 gets cancelled so it becomes 5² = 25.

[5-25]5^-1

$- 20 \times \frac{1}{5}$ as 5^-1 =1/5

So the final answer is

-4
