Answer:

$9^{-5}$

Step-by-step explanation:

By using indices rule, $\frac{x^{m} }{x^{n} }= x^{m-n}$

$\frac{9^2}{9^7}= 9^{2-7} = 9^{-5}$

4 = 3/4m - 6 pls help me ASAP and check the answer

laila [671]

Answer:

m = 3/40

Step-by-step explanation:

4 = 3/4m - 6

m*4 = m(3/4m -6)

4m = m*3/4m + m*-6

4m = 3/4 - 6m

6m + 4m = 3/4

10m = 3/4

m = (3/4)/10

m = 3/40

check:

4 = 3/(4*3/40) - 6

4 = 3/(12/40) - 6

4 = (3*40)/12 - 6

4 = 120/12 - 6

4 = 10 - 6

Which expression is eq to (125^2/125^4/3)

sweet [91]

Answer:

Step-by-step explanation:

So the denominator can be simplified to 5⁴ → $(5^3)^\frac{4}{3}$ and then the 3's cancel out and we are left with 5⁴

Now our new fraction is $\frac{125^{2} }{5^{4} } = \frac{15625}{625}$ which then simplifies to 25
