Question

please do will mark brainliest please HELPPP idk to do​

Answer 1

Answer:

$\huge \mathfrak\red{ \frac{ {3}^{ - 5} \times {10}^{ - 5} \times 125 }{ {5}^{ - 7} \times {6}^{ - 5} } = \frac{ {3}^{ - 5} \times {10}^{ - 5} \times {5}^{3} }{ {5}^{ - 7} \times {6}^{ - 5} } }$

$\huge \mathfrak\red{ = \frac{ {5}^{7} \times {6}^{5} \times {5}^{3} }{ {3}^{5} \times {10}^{5} } = \frac{ {5}^{10} \times {6}^{5} }{ {3}^{5} \times {10}^{5}}}$

$\huge \mathfrak\red{ = \frac{9765625 \times 7776}{243 \times 100000} }$

$\huge \mathfrak\red{ = \frac{3125 \times 32}{16 \times 1} = 3125}$

PLEASE MARK ME BRAINLIEST

Answer 2

Step-by-step explanation:

Here your Answer Army ♡

$\frac{3 {}^{ - 5} \times 10 {}^{ - 5} \times 125}{5 {}^{ - 7} \times 6 {}^{ - 5} } \\ = \frac{3 ^{ - 5} \times (2 \times 5) {}^{ - 5} \times (5 {}^{3} )}{5 {}^{ - 7} \times (2 \times 3) {}^{ - 5} } \\ = \frac{3 {}^{ - 5} \times 2 {}^{ - 5} \times 5 {}^{ - 5} \times 5 {}^{3} }{5 {}^{ - 7} \times 2 {}^{ - 5} \times 3 {}^{ - 5} } \\ = \frac{3 {}^{ - 5} \times 2 {}^{ - 5} \times 5 {}^{( - 5 + 3)} }{5 {}^{ - 7} \times 2 {}^{ - 5} \times 3 {}^{ - 5}} \\ = 3 {}^{ - 5 - ( - 5)} \times 2 {}^{ - 5 - ( - 5)} \times \frac{5 {}^{ - 2} }{5 {}^{ - 7} } \\ = 3 {}^{0} \times 2 {}^{0} \times 5 {}^{ - 2 - ( - 7)} \\ = 1 \times 1 \times 5 {}^{ - 2 + 7} \\ = 5 {}^{5} = 3125$
