Home » Aptitude » Surds and Indices » Question

Solve the below equation.
17^3.5 x 17^7.3 ÷ 17^4.2 = 17^?

1. 8.4
2. 8
3. 6.6
4. 6.4
5. None of the above

Correct Option: C

17^3.5 x 17^7.3 ÷ 17^4.2 = 17^?
Apply the Laws of Exponents ::
(a^m) x (aⁿ) = a^m+n
Fractional Exponents ::
a^m÷ a ⁿ=a^m?n
⇒ 17^{3.5 + 7.3 - 4.2} = 17^?
⇒ 17^6.6 = 17^?
∴ ? = 6.6
