Answer :

To solve the expression [tex]\(\left(\frac{2}{3}\right)^{-0.75}\)[/tex], we need to follow these steps:

1. Understanding the Exponent:
- The exponent [tex]\(-0.75\)[/tex] is negative, which means we need to find the reciprocal of the base raised to the positive of that exponent.

2. Rewrite the Expression:
- Rewrite [tex]\(\left(\frac{2}{3}\right)^{-0.75}\)[/tex] as [tex]\(\frac{1} {\left(\frac{2}{3}\right)^{0.75}}\)[/tex].

3. Evaluate the Positive Exponent:
- Calculate [tex]\(\left(\frac{2}{3}\right)^{0.75}\)[/tex]. This step involves raising the fraction [tex]\(\frac{2}{3}\)[/tex] to the power of [tex]\(0.75\)[/tex].

4. Reciprocal of the Result:
- Once you have [tex]\(\left(\frac{2}{3}\right)^{0.75}\)[/tex], take the reciprocal of this value to account for the negative exponent.

Following these steps, the evaluation yields the result:

[tex]\[ \left(\frac{2}{3}\right)^{-0.75} \approx 1.3554030054147672 \][/tex]

So, [tex]\(\left(\frac{2}{3}\right)^{-0.75}\)[/tex] approximately equals [tex]\(1.3554030054147672\)[/tex].
