Is f(x)=3x5^2x-3 an exponential function? If so, write it in the form f(x)=ab^x
Anna11 [10]

Answer:

f(x)=\frac{3}{125} * 25^x

Step-by-step explanation:

Given

f(x)=3*5^{2x-3}

Required

To determine if it is an exponential function, we have to write in form of

f(x) = ab^x

If we're able to do so, then the function is an exponential function.

If otherwise, then it is not

f(x)=3*5^{2x-3}

Apply Law of indices

f(x)=3*\frac{5^{2x}}{5^3}

Express 5^3 as 125

f(x)=3*\frac{5^{2x}}{125}

Factorize the exponent of 5

f(x)=3*\frac{5^{(2)x}}{125}

Express 5^2 as 25

f(x)=3*\frac{25^x}{125}

This can be rewritten as:

f(x)=\frac{3}{125} * 25^x

By comparing the above to f(x) = ab^x

We have that

a = \frac{3}{125}

b^x = 25^x

Since, we've be able to express the function as f(x) = ab^x

Then, f(x)=3*5^{2x-3} is an exponential function

What is bigger 5/6 or 11/12?
Maurinko [17]
First you find the common deoninator.
Step 1: Reduce (simplify) entered fractions to lowest terms, if the case:Fraction: 5 / 6 it's already reduced to lowest terms
Fraction: 11 / 12 it's already reduced to lowest terms
Step 2: Calculate LCM (lowest common multiple) of the reduced fractions' denominators, it will be the common denominator of the compared fractions:Denominator 6, factored = 2 * 3
Denominator 12, factored = 22<span> * 3</span>
LCM (6, 12) = 22<span> * 3 = 12</span>Step 3: Calculate each fraction's expanding number (LCM divided by each fraction's denominator):For fraction: 5 / 6 is 12 : 6 = (22<span> * 3) : 6 = 2</span>
For fraction: 11 / 12 is 12 : 12 = (22<span> * 3) : 12 = 1</span>
Step 4: Expand fractions to bring them to the common denominator (LCM):5 / 6 = (2 * 5) / (2 * 6) = 10 / 12
<span>11 / 12 = (1 * 11) / (1 * 12) = 11 / 12</span>
