Question

please answer me fast it's important​

Answer 1

$a {}^{0} = 1 \\ x {}^{m} x {}^{n} = x {}^{m + n} \\ x {}^{ - a} = \frac{1}{x {}^{a} } \\ x {}^{a} \div {y}^{a} = (\frac{x}{y} ) {}^{a}$

Answer 2

1. a°=1 anything whose power is o is equal to 1
2. ${x}^{m} \times {x}^{n } = {x}^{m + n}$
3. ${x}^{ - a} = x \div a$
4. ${x}^{a } \div {y}^{a} = ( {x \div y)}^{a}$
