Question

What is the answer to c to the fifth power, times c to the eighth power, times c to the negative fifth power?

Answer 1

c^8

Explanation:

Expressing the above Mathematically ;

c^5 * c^8 * c^-5

From.rules of indices :

a^x * a^y = a^(x + y)

Therefore, applying the rule of indices ;

c^5 * c^8 * c^-5 = c^(5 + 8 + - 5)

c^5 * c^8 * c^-5 = c^(5 + 8 - 5)

c^5 * c^8 * c^-5 = c^8

Hence,

c^5 * c^8 * c^-5 = c^8
