Simplifying exponents (picture provided)
Hitman42 [59]

Answer:

<em>3^2 ; Option B</em>

Step-by-step explanation:

We are given the equation 3^ -6 * ( 3^4 / 3^0 )^2, which can be solved through the application of exponential rules;

3^{ - 6 } * ( 3^{ 4 } / 3^{ 0 } )^{2} - take 3^{ 0 } as 1,\\\\3^{ - 6 } * ( 3^{ 4 } / 1 )^{2} - take 3^{4} to power of 2, ( * of exponents ),\\\\3^{ - 6 } * ( 3^{ 8 } ) - combine powers, adding exponents,\\\\3^{ - 6 + 8 } - add like terms,\\\\3^{2} \\\\Solution; 3^{2}

<em>3^2 ; Option B</em>

Which term can be cancelled out of the expression​
Lubov Fominskaja [6]

Answer:

x+3

Step-by-step explanation:

If you factor 5 out of the denominator of the first expression, 5x+15 turns into 5(x+3).  

Then, since you have x+3 in the numerator and denominator, it will cancel out.

The steps are shown below:

\frac{7x}{5x+15} *\frac{x+3}{8} \\\\=\frac{7x}{5(x+3)} *\frac{x+3}{8} \\\\=\frac{7x}{5} *\frac{1}{8} \\\\=\frac{7x}{40}\\

Ive attached an image that shows an example of simplifying an expression using a the same technique.
