Step-by-step explanation: To find the exponent, we look at the expression again and see how much of the same number or fraction is repeated. Since the main number is 1/9 and there are 3 fractions repeating it, the exponent is or 1/9 to the 3rd power.
<em>Down is a formula I made!</em>
Main number: 1/9
Repeating how many times: 3
Expression:
Therefore, 1/9 to the 3rd power is 1/729.
<em>Note: The questioner did not ask for the answer. I wanted to add it anyway for future reasons.</em>
Answer :-
Step by step explanation :-
- <u>Unitary</u><u> </u><u>method</u><u> </u><u>:</u><em><u>-</u></em><em><u> </u></em>
Cost of 10 balls = 36
Cost of one ball = 36 / 10 => 3.6
Cost of 48 balls = 48 × 3.6
=> 172.80
- <u>Direct</u><u> </u><u>Variation</u><u> </u><u>method</u><u> </u><u>:</u><u>-</u><u> </u>
No. of balls (a)

Answer:
Step-by-step explanation:
Perimeter of a polygon = Sum of the measures of all sides of the polygon
For the given trapezoid,
Perimeter =
By combining similar terms,
Perimeter =
=
= (2 + 1)a +
= 3a +
= 3a +
= 3a +
= 3a +
For rectangle,
Perimeter = 2(Length + Width)
= 2(2a + 3b)
Difference between the perimeter of trapezoid and rectangle,
= (3a + ) - 2(2a + 3b)
= (3a - 4a) + ( - 6b)
= -a +
= -a +
= -a +
= -a -
=
