We know that
area of the square=b²-------> b=√area
where
b is the side length of the square

for the smaller square
area=256 m²
b=√256-------> b=16 m

for the larger square
area=625 m²
b=√625-----> b=25 m

<span>the ratio of their sides is 16/25</span>

Which is the simplified form of (2ab/a^-5 b^2)^-3?

Sever21 [200]

I am using the laws:
1) $( x^{a} )^{c} = x^{a*c}$
2) $x^{a} * x^{b} = x^{a+b}$
3) $\frac{ x^{a} }{x^{b}} = x^{a-b}$

an x is a base - the law is valid if the bases are the same number!

The solution in attachment :)
