5 x 3^n
(This is all i have for the question but i don't know how to solve it)
Oh !
5*3^1 = 15
5*3^2 = 5*9 = 45
45* 3 = 135
135 * 3 = 405
nor do I unless you have a value for n
The choices are:
A. 15, 30, 45, 60
B. 5, 15, 45, 135
c. 0, 15, 45, 135
D. 15, 45, 135, 405
But I'm not sure how you find those answers??
To solve the expression 5 x 3^n, we need to understand the rules of exponentiation. In this case, the exponent "n" is applied to the base number 3. Let's break down the steps to find the answer:
Step 1: Start with the base number, which is 3.
Step 2: Raise 3 to the power of "n". This means multiplying 3 by itself "n" times.
Step 3: Multiply the result of step 2 by 5.
Let's look at a few specific examples to understand how this works:
Example 1: If n = 0
In this case, 3^0 equals 1 (any number raised to the power of 0 equals 1). So, the calculation becomes 5 x 1 = 5.
Example 2: If n = 1
In this case, 3^1 equals 3 (any number raised to the power of 1 is the number itself). So, the calculation becomes 5 x 3 = 15.
Example 3: If n = 2
In this case, 3^2 equals 9 (3 multiplied by itself). So, the calculation becomes 5 x 9 = 45.
Example 4: If n = 3
In this case, 3^3 equals 27 (3 multiplied by itself, then multiplied by itself again). So, the calculation becomes 5 x 27 = 135.
As you can see, the value of "n" affects the result of the expression. You can substitute any value for "n" and follow the same steps to find the answer.
