Answer 1

Question :

• x⁵ . x³
• x⁸/x³
• (x³)²
• (3x²)³
• (5x-³ yz²)-²

Answer :

• x⁵ . x³

x⁵ . x³ = x⁵+³

➜ x⁸

• x⁸/x³

x⁸/x³ = x⁸-³

➜ x⁵

• (x³)²

(x³)² = x³×²

➜ x⁶

• (3x²)³

(3x²)³ = 3x²×³

➜ 3x⁶

• (5x-³ yz²)-²

(5x-³ yz²)-² = 1/5x³ - yz²

➜ 1/25x⁶+y²z⁴-10x³yz²

★ Important identities :

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

• $\sf{\dfrac{{a}^{m}}{{a}^{n}} = {a}^{m-n}}$

• $\sf{{(ab)}^{m} = {a}^{m}{b}^{m}}$

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