(x^m)^n=x^(mn)
ok so
(3^2)(2a)^(3/2))^2=
(3^2)(2a)^((3/2)*2)=
(3^2)(2a))^(6/2)=
(3^2)(2a)^3=
(3^2)(8a^3)^3=
(9)(8a^3)=
72a^3
2nd one from left
The equation that Mr. Brown could use to complete the system is 1.25x + 0.5y = 2 so that it has infinite solutions.
For the shaded bit all you need to do is 8.5 × 6.
if you are to get the other bit then do 8.5 × 8
if it is to be both then just do that and add them together
The answer is fifty one (51)
