Answer 1

98,000

Explanation:

`5^(4) *7^(5)* 2^(8)/16*125*7^(3)`

`=5^(4) * 7^(5)* 2^(8) /2^(4) *5^(3) *7^(3)`

`=5^(4-1) *7^(5-3) *2^(8-4)`

=
`5^(3) *7^(2) *2^(4)`

=
`125*49*16`

`=98000`

Answer 2

Explanation:

Factorize all the numbers in numerator and denominator

16 = 2*2*2*2

125 = 5 *5 *5

`(a^(m))/(a^(n))=a^(m-n)`, where m >n

`(5^(4)*7^(5)*2^(8))/(16*125*7^(3))=(5^(4)*7^(5)*2^(8))/(2^(4)*5^(3)*7^(3))\\\\\\=5^((4-3))*7^((5-3))*2^((8-4))\\\\\\=5^1*7^2*2^(4)`
