Question

all formulas of class 8 maths Ch exponent and power​

Answer 1

Answer:

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

$\frac{ {a}^{m} }{ {a}^{n} } = {a}^{m - n}$

${a}^{0} = 1$

${ ({a}^{m} )}^{n} = {a}^{m \times n}$

${a}^{m} \times {b}^{m} = ({ab})^{m}$

${a}^{ - m} = \frac{1}{ {a}^{m} }$

Hope it will helps you...

Answer 2

Step-by-step explanation:

Laws of Integral Exponents

For any two real numbers a and b, a, b ≠ 0, and for any two positive integers, m and n

➲ If a be any non - zero rational number, then

a^0 = 1

➲ If a be any non - zero rational number and m,n be integer, then

(a^m)^n = a^mn

➲ If a be any non - zero rational number and m be any positive integer, then

a^-m = 1/a^m

➲ If a/b is a rational number and m is a positive integer, then

(a/b)^m = a^m/b^m

➲ For any Integers m and n and any rational number a, a ≠ 0

a^m × a^n = a^m+n

➲ For any Integers m and n for non - zero rational number a,

a^m ÷ a^n = a^m-n

➲ If a and b are non - zero rational numbers and m is any integer, then

(a+b)^m = a^m × b^m
