Find the value of each of the following:
( i ) `8^(@)`
( ii ) `(-3)^(@)`
( iii ) `4^(@)+5^(@)`
( iv ) `6^(@) xx 7^(@)`

Answer

To solve the question, we will evaluate each part step by step.

### Step-by-Step Solution:

**(i) Calculate \( 8^0 \)**
According to the exponent rules, any non-zero number raised to the power of 0 is equal to 1.
Thus,
\[ 8^0 = 1 \]

**(ii) Calculate \( (-3)^0 \)**
Similarly, for negative numbers, the same rule applies.
Thus,
\[ (-3)^0 = 1 \]

**(iii) Calculate \( 4^0 + 5^0 \)**
Using the same rule:
\[ 4^0 = 1 \]
\[ 5^0 = 1 \]
Now, add the two results:
\[ 4^0 + 5^0 = 1 + 1 = 2 \]

**(iv) Calculate \( 6^0 \times 7^0 \)**
Again, applying the exponent rule:
\[ 6^0 = 1 \]
\[ 7^0 = 1 \]
Now, multiply the two results:
\[ 6^0 \times 7^0 = 1 \times 1 = 1 \]

### Final Answers:
- (i) \( 8^0 = 1 \)
- (ii) \( (-3)^0 = 1 \)
- (iii) \( 4^0 + 5^0 = 2 \)
- (iv) \( 6^0 \times 7^0 = 1 \)
