This is maths question related to chapter exponents and power

Answer 1

$\dfrac{3^{-5} \times 10^{-5} \times 125} {5^{-7} \times 6^{-5}}$

$= 3^{-5} \times 10^{-5} \times 5^3 \times 5^{7} \times 6^{5}$

$= 3^{-5} \times 2^{-5} \times 5^{-5} \times 5^3 \times 5^{7} \times 2^{5} \times 3^{5}$

$= 3^{-5+5} \times 2^{-5 + 5} \times 5^{-5+ 3 + 7}$

$= 3^{0} \times 2^{0} \times 5^{5}$

$= 1\times 1 \times 5^{5}$

$= 5^5$

Answer: 5⁵
