1. Write down the expression 2. How many times do you have to multiply 4 by itself to get 256?

1. The expression is:

• \[ \frac{1}{3} \times \frac{1}{3} \times \frac{1}{3} \times ... \text{ (n times)} \times \frac{1}{3} \text{ or } \left( \frac{1}{3} \right)^n \]

2. Calculation:

1. Let the number of times 4 is multiplied by itself be 'n'.
2. The equation is: \( 4^n = 256 \)
3. We need to find the value of 'n'.
4. We know that:
• \( 4^1 = 4 \)
• \( 4^2 = 16 \)
• \( 4^3 = 64 \)
• \( 4^4 = 256 \)
5. Therefore, \( n = 4 \).
