Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking.

can you please check again the Utility function? is it $U=f({G_1},{G_2})=45{{G_1}^{0.7}}{{G_2}^{0.3}}$ because you have , which does not make sense unless it is a general function. And also what do you want to achieve? do you want to have a Marginal utility with respect to $G_1$ and Marginal utility with respect to $G_2$?

# Utility Function Challenge

(Asked by: username_0 on 2021-11-25)

A utility function is given for two goods

Good 1 and Good 2
$$U=f({G\_1},{G\_2})=45{{G\_1}^{0.7}}{{G\_2}^{0.3}}$$

1. Did I get this right? the marginal utility functions with respect to G1 and G2 will be following:

$\frac{\partial{U}}{\partial{G\_1}}$ $\implies$ $MU$ of Good 1

$\frac{\partial{U}}{\partial{G\_2}}$ $\implies$ $MU$ of Good 2

$$U=f({G\_1},{G\_2})=45{{G\_1}^{0.7}}{{G\_2}^{0.3}}$$

2. Total differential of this utility function should be:

$$d{U} = d{f}= f{G\_1}({G\_1},{G\_2})d{G\_1} + f{G\_2}({G\_1},{G\_2})d{G\_2}$$

Are these workings right?

The solution to question

1. Your Solution is correct.
2. To get the total differential use the following formula

$$d{U} = d{f}= \frac{\partial{U}}{\partial{G\_1}}d{G\_1} + \frac{\partial{U}}{\partial{G\_2}}d{G\_2}$$
