## Exponents and powers class 8 formulas

• $x^{m} \times x^{n}=x^{m+n}$
• $x^{m} \div x^{n}=x^{m-n}$
• $x^{m} \times b^{m}=(x b)^{m}$
• $x^{0}=1$
• $\frac{x^{m}}{y^{m}}=\left(\frac{x}{y}\right)^{m}$
• $\left(\frac{x}{y}\right)^{n}=\left(\frac{y}{x}\right)^{-n}$
• $\frac{1}{x}=x^{-1}$
• $x^{p} \times x^{q} \times x^{r} \times x^{s}=x^{p+q+r+s}$
• $\left[\left(x^{m}\right)^{n}=x^{m n}\right]$
• If a, b are non-zero integers and m, n are any integers, then

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

(ii) $\frac{a^{m}}{a^{n}}=a^{m-n}$

(iii) $\left(a^{m}\right)^{n}=a^{m n}$

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

(v) $\frac{a^{m}}{b^{m}}=\left(\frac{a}{b}\right)^{m}$

(vi) $a^{0}=1$

(vii) $\left(\frac{a^{-m}}{b^{-n}}\right)=\frac{b^{n}}{a^{m}}$

(viii) $\left(\frac{a}{b}\right)^{-m}=\left(\frac{b}{a}\right)^{m}$
