Express 256 as a power 4.a)48b)44c)45d)42Correct answer is option 'B'....
To express 256 as a power of 4, we need to find the exponent that, when raised to 4, gives us the value of 256.
Let's start by finding the square root of 256. The square root of a number is the value that, when multiplied by itself, gives the original number. In this case, the square root of 256 is 16 because 16 * 16 = 256.
Now, let's find the square root of 16. It is 4 because 4 * 4 = 16.
Since the square root of 16 is 4, and we are looking for a power of 4, we can express 256 as 4 to the power of 4.
Therefore, the correct answer is option 'B' (44).
Here's a step-by-step breakdown:
1. Find the square root of 256: √256 = 16
2. Find the square root of 16: √16 = 4
3. Express 256 as a power of 4: 4^4 = 256
Let's start by finding the square root of 256. The square root of a number is the value that, when multiplied by itself, gives the original number. In this case, the square root of 256 is 16 because 16 * 16 = 256.
Now, let's find the square root of 16. It is 4 because 4 * 4 = 16.
Since the square root of 16 is 4, and we are looking for a power of 4, we can express 256 as 4 to the power of 4.
Therefore, the correct answer is option 'B' (44).
Here's a step-by-step breakdown:
1. Find the square root of 256: √256 = 16
2. Find the square root of 16: √16 = 4
3. Express 256 as a power of 4: 4^4 = 256
