It's 6!
When you multiply both the numerator and denominator by the same number, you will have an equivalent to the fraction you started with because the new fraction can be reduced to the original fraction.
2/3 = 4/6 = 6/9 = 8/12 = 10/15 = 12/15 etc.
300 / 0.06 = 5000
answer <span>Three hundred is 6 percent of 5,000

You first multiply the outside exponents into the numbers in the parentheses.
When you have an exponent being multiplied directly to another exponent, you multiply the exponents together.
For example(because I am a bad explainer):


When you divide an exponent by an exponent, you subtract the exponents
For example:

When you have a negative exponent, you move it to the other side of the fraction to make the exponent positive
For example:



You can think of it like this if you want:
Now multiply the outside exponents into the exponents in the parentheses
Divide 27 and 9

Your answer is 
Y=sqrt(3x+4)
3x+4 must be positive
3x+4>=0
Solving for x:
3x+4-4>=0-4
3x>=-4
3x/3>=(-4)/3
x>=-(4/3)
Domain of the function = [-(4/3), +Infinite)
