To divide numbers with the same base, keep the base and subtract the indices. When raising a power to a power, keep the base and multiply the indices. The power of a product is the product of the powers. The power of a quotient is the quotient of the powers. Any non-zero number raised to the power of zero is 1. 1 and in particular a-1 Example & Hio

所 *neaa 本日 9 次のガンディー(Gandhi)の伝記の一部を読んで, あとの問いに答えなさい。 教科書| p.76 Gandhi moved to South Africa to work as a lawver in 1893. It was under British rule at that time and there was a lot of discrimination. For example, Indians could not go out at night freely or walk on the sidewalk. There were also (-did/ hotels/Indian guests / aceept / net/ that ). In 1906, the British made a law that was even more unfair to Indian people. Indians in South 2 5 Africa got angry and stood up against the law. Gandhi decided to lead a movement to protect their rights. His message was “Don't follow the law, but don't use violence, even if you are arrested." Soon the jails became full of Indians, and Gandhi himself was sent there.
