Answer 2

Answer: $\sf {(\frac{ - 2}{3})}^{3} \times {(\frac{ - 2}{3})}^{4}$

Step-by-step explanation:

❍ Solution :-

$\sf →{(\frac{ - 2}{3})}^{3} \times {(\frac{ - 2}{3})}^{4}$

We know that,

➸ $\sf {a}^{m} \times {a}^{n} = {a}^{m + n}$

$\sf →{(\frac{ - 2}{3})}^{3 + 4}$

$\sf →{(\frac{ - 2}{3})}^{7}$

$\sf →\fbox{(\dfrac{ - 128}{2187})}$

Hence, $\sf {(\frac{ - 2}{3})}^{3} \times {(\frac{ - 2}{3})}^{4}$ is equal to $(\dfrac{ - 128}{2187})$.

✏ $\sf {a}^{m} \times {a}^{n} = {a}^{m + n}$

✏ $\sf {a}^{m} \div {a}^{n} = {a}^{m - n}$

✏ $\sf {{a}^{m}}^{n} = {a}^{mn}$

✏ $\sf {a}^{ - x} = \frac{1}{{a}}^{x}$

✏ $\sf {a}^{0} = 1$
