Answer 1

Answer:

5^-9

Step-by-step explanation:

$\bigstar{\underline{\underline{{\sf\ \red{ Given:-}}}}}$

$\frac{3^{-5×10^{-5}×125 } }{5^{-7} ×6^{-5} }$

$\bigstar{\underline{\underline{{\sf\ \red{ To \: Find:-}}}}}$

To simplify.

$\bigstar{\underline{\underline{{\sf\ \red{ Solution:-}}}}}$

Using a^m× b^m = (ab)^m

⇒ (3×10)^-5 = 30^-5

Now, We noticed that 125 is a perfect cube.

So we can write it as 5^3

Using a^m÷a^n= a^m-n

⇒ 5^3÷ 5^-7

⇒ 5^-4

Using a^m÷b^m= (a/b)^m

⇒ (30/6)^-5

⇒ 5^-5

Using a^m× a^n= a^m-n

⇒ 5^(-5-4)

⇒ 5^-9

Therefore, The simplified answer is 5^-9.
