Question

please answer anyone one of the above question
please
help me out...​

Answer 1

♛HELLO♛

i)$x^5\cdot x^3 = x^{5+3}= x^8$

ii)$\frac{x^8}{x^3} = x^{(8-3)} = x^5$

iii)$(x^3)^2 = x^{3\cdot2}= x^6$

iv)$(5x^{-3}yz^2)^{-2 }= \frac{1}{\left(5x^{-3}yz^2\right)^2} = \frac{1}{\frac{25y^2z^4}{x^6}} = \frac{x^6}{25y^2z^4}$

Answer 2

1. x^(5+3) = x^8

2. x^(8-3) = x^5

3 (x³)² = x^6

4. (3x²)³ = 27x^6

5. (5×1/x³×yz²)^-2 = x³/5×1/y×1/z²
