Add the exponents and keep the same base. Then reciprocal it and change the sign of the exponent. Then the value of the exponent expression is 0.5.
<h3>What is an exponent?</h3>
Exponential notation is the form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter is called the base. It indicates that the base is to raise to a certain power. X is the base and n is the power.
The exponent expression is 2³ × 2⁻⁴ can be simplified.
Add the exponents and keep the same base. Then we have
2³ × 2⁻⁴ = 2⁽³⁻⁴⁾
2³ × 2⁻⁴ = 2⁻¹
Then find the reciprocal and change the sign of the exponent.
The value is 0.5.

The answer is 36 because in order to find area you multiply length and width so:
A= L x W
9 x 4 = 36
The answer is 43 because it is half of 86 which is the radius
Answer:
Initial temperature;
432.76
Common ratio;
-0.067
Equation;
Step-by-step explanation:
In this scenario, the time in minutes represents the independent variable x while the temperature of the pizza represents the dependent variable y.
The analysis is performed in Ms. Excel. The first step is to obtain a scatter plot of the data then finally inserting an exponential trend line to obtain the required equation.
The Ms. Excel output is shown in the attachment below. To obtain the initial temperature we substitute x = 0 in the equation. On the other hand, the common ratio is the exponent in the equation.
Answer:−9a+10b−23
Step-by-step explanation:−9a+3b−a+7b−13+a−10
Combine −9a and −a to get −10a.
−10a+3b+7b−13+a−10
Combine 3b and 7b to get 10b.
−10a+10b−13+a−10
Combine −10a and a to get −9a.
−9a+10b−13−10
Subtract 10 from −13 to get −23.
−9a+10b−23
