Question

Raise r to the 7th power, then double the result

Answer 1

Answer:

$\huge\boxed{\bf\:2r^{7}}$

Step-by-step explanation:

Let the variable be taken as 'r'.

Then, by raising it to the 7th power, we'll get the result as $\downarrow$

 $\sf\:Raise \: r \: to \: the \: 7^{th} \: power = r \: with \: 7 \: as \: its \: exponent.\\\\\sf\:Then,\\\dashrightarrow \underline{\bf\:r \: ^{7}}$

Now, by doubling the result....

$\sf\:To \: double \: the \: result = multiply \: the \: result \: by \: 2.\\\\\sf\:Then,\\\dashrightarrow \sf\:r \: ^{7} \\=\boxed{\bf\: 2r\:^{7}}$

$\rule{150pt}{2pt}$

Answer 2
