Answer:
Area of the rectangular piece of card = 96 sq.cm
Step-by-step explanation:
here we go,
peremeter ( p ) = 2 × ( length (L) + width (B) )
so,
=》40 = 2 ( L + 8 )
=》40 / 2 = L + 8
=》20 = L + 8
=》L = 20 - 8
=》L = 12
so, length of the card = 12cm
now,
Area (A) = length (L) × width (B)
=》A = 12 × 8
=》Area = 96 sq.cm
Answer:

Q1. The answer is <span>1 over 5 to the 3rd power.
</span>5 to the 5th is 5⁵
5 to the 8th is 5⁸
5 to the 5th over 5 to the 8th is

To simplify, we will use two rules:

Therefore:


is the same as 1 over 5 to the 3rd power.
Q2. The answer is <span>(53)−4.
The exponents are multiplied when are expressed in the form:
</span>

So,

Other choices are incorrect:
<span>one third to the 4th times one third to the 7th is </span>

3 to the 7th over 3 to the 15th is

<span>45 ⋅ 42 is </span>
