Question

Please help thanks!!

Answer 1

Number 1 is correct. Use the Product Rule x ^a+b

Answer 2

$\sqrt{5} \: can \: also \: be \: written \: as \: {5}^{ \frac{1}{2} } \\ \sqrt[3]{5} \: can \: also \: be \: written \: as \: {5}^{ \frac{1}{3} }$
when multiplying these, you add the exponents by finding the least common denominator. In this case, it is 6.
Now, convert the fraction exponents so their denominators are both 6:
1/2 = 3/6
1/3 = 2/6
Now simply add the fractions:
3/6 + 2/6 = 5/6

This is your new exponent, so:
$( \sqrt{5})( \sqrt[3]{5} ) = {5}^{ \frac{5}{6} }$
