Answer:
[tex]\Large \boxed{\sf A}[/tex]
Step-by-step explanation:
[tex]\displaystyle \left(\frac{2}{3}\right)^4[/tex]
n → exponent, means to multiply the base number by itself n no. of times.
Here we multiply the base number by itself 4 times.
[tex]\displaystyle \frac{2}{3}\cdot \frac{2}{3}\cdot \frac{2}{3}\cdot \frac{2}{3}[/tex]
Answer: A.
To expand a exponent, you'll find the number how much it powers by and expand it by what the power or exponent number represents.
The fraction is 2/3 and the exponent is 4. Like I've said before, to expand it you'll find the number how much it powers by.
In the equation, 2/3 is going to the 4th power, so we will expand the fraction 4 times.
2/3 × 2/3 × 2/3 × 2/3
is 2/3 to the 4th power in expanded form.
Hence, A is the answer.
