Final answer:
The student is likely dealing with solving for variables in algebra or physics equations, and there is mention of how to use a calculator for entering exponents and negative numbers.
Step-by-step explanation:
The question provided appears to be related to solving for specific variables, likely with algebraic expressions or physics equations. It's a bit unclear due to typos, but we can infer some mathematical processes:
Using a Calculator for Exponents
To calculate an exponent with a calculator, you often use the second function key (Shift or INV) to access the exponent function (usually above the LOG key). To enter a negative base, such as -8.3 to the power of 10, you would use the +/- key before entering the 8.3.
Finding Unknown Variables
When determining the equation to use for solving for an unknown variable, select an equation where all other variables are known. For instance, if you need to find 'w' without a time variable (t), and you know the initial velocity (wo) and acceleration (a), you would use the equation w² = wo² + 2a0.
