Answer 1

echo "pow(5.0, 3.0) = " . pow(5.0, 3.0) . "<br />";
echo "pow(3.14, 10.0) = " . pow(3.14, 10.0) . "<br />";
echo "pow(31.15, 1.43) = " . pow(31.15, 1.43) . "<br />";
echo "pow(4, 0.5) = " . pow(4, 0.5) . "<br />";
echo "pow(-3, -2) = " . pow(-3, -2) . "<br />";


/*
run:
    
pow(5.0, 3.0) = 125
pow(3.14, 10.0) = 93174.373386644
pow(31.15, 1.43) = 136.66113173141
pow(4, 0.5) = 2
pow(-3, -2) = 0.11111111111111
