Which expression is equivalent to (3m^-1n^2)^4/(2m^-2n)^3?

Step-by-step explanation:

Given is an expression involving exponents of m and n.

We have to simplify and give the answer

Numerator is given as

Denominator =

Now simplify first constant term then m term and n term

i) 81/8 is the first term

ii)

iii)

Combining everything we get

answer as

x=2 & x=1

step-by-step explanation:

7*1=7

7*2=14

7 is less than 21

14 is less than 21

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had
