Your calculator cannot solve this problem for you. All you need is a knowledge of basic algebra and exponets:

6.3*10^-4 = 4x^3.
Divide both sides by 4:
x^3 = 1.575*10^-4
Take cube root of both sides:
(x^3)^(1/3) = (1.575*10^-4)^(1/3)
X = 1.1635*0.046416 = 0.05401.

Note: You can take the cube root of a
number by raising it to the 3rd power.

To solve the equation 6.3 * 10^(-4) = 4x^3 on a calculator, you will need to use the appropriate buttons and functions to input the equation and calculate the value of x. Here's a step-by-step guide on how to do this:

Step 1: Start by entering the equation into your calculator. Here's how to input it:
- Enter "6.3" using the numerical keypad.
- Press the Multiplication (*) button.
- Enter "10". Usually, there is a dedicated button for entering scientific notation on calculators. Look for an "EE" or "^" button and press it.
- Enter "-4", corresponding to the exponent.
- Press "=" or "Enter" to complete the equation input.

Step 2: Now, you will need to rearrange the equation to isolate x. Divide both sides of the equation by 4 to get x^3:
- Press the Division (/) button.
- Enter "4".
- Press "=" or "Enter" to divide 6.3 * 10^(-4) by 4.

Step 3: Take the cube root of the result to solve for x:
- Press the cube root (∛) or power (^) button (if it allows entering fractional exponents).
- Enter the result from step 2.
- Press "=" or "Enter" to calculate the cube root of the result.

The value displayed on the calculator after following these steps will be the solution to the equation, representing the value of x.
