Question

For a non-zero rational number x, x⁸ ÷ x² is equal to ______.

Options

• x⁴

• x⁶ 

• x¹⁰

• x¹⁶

Answer 1

For a non-zero rational number x, x⁸ ÷ x² is equal to `bb(underline(x^6))`.

Explanation:

For any non-zero integers ‘a’ and ‘b’ and whole numbers m and n,

a^m ÷ aⁿ = a^m–n, m > n

So, x⁸ ÷ x² = `x^8/x^2` = x^8–2 = x⁶
