1/3^5

When multiplying exponents you just add them. X^a x X^b = X^a+b

If you have a negative exponent, you flip it to be the denominator (if originally numerator) or numerator (if originally denominator.

So, 3^-5 = 1/3^5

Divide 800ml into ratio 3:7
Black_prince [1.1K]
Simply take the numerator (3) and denominator (7) and add them together. 

3+7 = 10, which means that the ratio will provide parts that are in multiples of 10 depending on the total

so take 10x = 800 

x = 80.

Then multiply this by the numerator and denominator 

3*80/7*80 = 240/560.
