Step-by-step explanation:
By Law of Indices, (a^m)^n = a^(mn).
Hence (h²)^(-3) = h^(-6) or 1/h⁶.

Given:
_____________________________________________________
" (2x <span>− 2y) (2y + 8) " ; Simplify .
_____________________________________________________
We starting by "expanding" the expression.
_____________________________________________________
<u>Note</u>: " (a + b)(c + d) = ac + ad + bc + bd " ;
_____________________________________________________
</span>→ (2x * 2y) + (2x * 8) + (-2y * 2y) + (-2y * 8) ;
= 4xy + 16x + (- 4y² ) + (-16y) ;
= 4xy + 16x − 4y² <span>− 16y ;
</span>→ which is: "Answer choice: [D]: " 4xy + 16x − 4y² − 16y " .

Answer:
45 and 225
Step-by-step explanation:
Let x represent the larger number. Then ...
x - 1/5x = 180
x = 5/4(180) = 225
1/5x = 45
The two numbers are 45 and 225.
