Answer 2

Answer:

The correct answer is 2.

Step-by-step explanation:

The following question is based on the laws of indices.

An index, or power, is the small floating number that appears after a number or letter. The plural of index is indices. Indices show how many times a number or letter has been multiplied by itself.

Given,

($5^0 + 6^0 + 7^0 + 8^0$) * (1/2)

According to one of the laws of the indices, if a number has the power as zero, it becomes 1, i.e.

$x^0$ $= 1$

On applying this on the given question, we get

⇒ ($5^0 + 6^0 + 7^0 + 8^0$) * (1/2)

⇒ (1+1+1+1) x (1/2)

⇒ 4/2

⇒ 2

Hence the answer is 2.
