You can use the properties of logarithm to get to the solution.
The approximate value for given term is given by
When you raise a number with an exponent, there comes a result.
Lets say you get
Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows
Some properties of logarithm are:
Thus,
The approximate value for given term is given by

Answer:
60 grams
Step-by-step explanation:
For these type of questions, we can equate the ratio with the actual amounts. We will let the quantity to find be an unknown variable, such as x. Then we equate the ratios, cross multiply, and use algebra to solve.
Let grams of zinc be "x", so we can write the ratios and actual amounts as:
Then we cross multiply and solve for x, what we want to find out. Shown below:
There are 60 grams of zinc.
