What is the simplified base for the function f(x) = 2rootindex 3 startroot 27 endroot superscript 2 x?
VMariaS [17]

Applying exponential properties, the simplified base for the function is given as follows:

f(x) = 2(3)^{2x}

<h3>What is the function?</h3>

The function is represented by the following definition:

f(x) = 2\sqrt[3]{27^{2x}}

As an exponent, the function is given by:

f(x) = 2(27)^{\frac{2x}{3}}

27 can be simplified as follows:

27 = 3 x 3 x 3 = 3³

Hence:

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

Then, the 3 at the exponent multiplies 2x and can be simplified with the 3 of the root, hence:

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

Hence the simplified base for the function is given as follows:

f(x) = 2(3)^{2x}

Todd says that he can make 10 if he adds 32 coins to 28 coins. Is he correct? Explain how you know using words.
Andreas93 [3]
He was wrong, you cannot make 10 coins by adding 32 coins to 28 coins. If you want to obtain 10 coins from 32 coins and 28 coins, you can subtract 28 coins from 32 coins.
This can be illustrated as follows:
32-28=10
