(2fg<sup>2</sup>)<sup>3</sup>(fg)<sup>4</sup>

Give every factor inside a parentheses the exponent 1 if
it does not have an exponent showing, whether it is a 
number or a letter:

(2<sup>1</sup>f<sup>1</sup>g<sup>2</sup>)<sup>3</sup>(f<sup>1</sup>g<sup>1</sup>)<sup>4</sup>

Remove the parentheses by multiplying every inside exponent
by the outside exponent:

2<sup>1*3</sup>f<sup>1*3</sup>g<sup>2*3</sup>f<sup>1*4</sup>g<sup>1*4</sup>

2<sup>3</sup>f<sup>3</sup>g<sup>6</sup>f<sup>4</sup>g<sup>4</sup>

Change the 2<sup>3</sup> to 2*2*2=8

8f<sup>3</sup>g<sup>6</sup>f<sup>4</sup>g<sup>4</sup>

Add the exponents of the f's
Add the exponents of the g's

8f<sup>3+4</sup>g<sup>6+4</sup>

8f<sup>7</sup>g<sup>10</sup>
