Answer:
Step-by-step explanation: l = 5 + w
p = 168
...
p = 2l + 2w
168 = 2(5+w) + 2w
168 = 10 + 2w + 2w
168 - 10 = 4w
158 = 4w
1 = 5 + 39.5

The simplification form of the number expression (2⁴)⁻¹ is 1/2⁴ option (B) one over two raised to the fourth power is correct.
<h3>What is an integer exponent?</h3>
In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.
It is given that:
The number expression is:
= (2⁴)⁻¹
Using the properties of the integer exponent:
= 1/2⁴
The above number is one over two raised to the fourth power
Thus, the simplification form of the number expression (2⁴)⁻¹ is 1/2⁴ option (B) one over two raised to the fourth power is correct.

Answer:
Ques 1: 7.85
Ques 2: both and are rational.
Ques 3: 0.9
Step-by-step explanation:
Ques 1:
Solving the , we get 7.8485.
Rounding off to nearest hundredth, we see that next digit is 8, so we increase the previous digit by 1.
So, the answer to nearest hundredth is 7.85.
Ques 2:
and to be checked whether they are rational or irrational.
We know that is equal to 4.
= -4 which is a rational value.
Let us solve now.
Which is a rational value.
So, both are rational.
Ques 3:
Simplify
0.81 can be written as in rational form.
Now, taking the square root, we need to take the square root for both Numerator and Denominator and then we can divide to get the desired square root.
So, the answers are:
Ques 1: 7.85
Ques 2: both and are rational.
Ques 3: 0.9
