Question

What is this, please help

Answer 1

4⁻¹⁷

Explanation:

let the box be represented by x

4⁻⁹ = 4⁸ * X

divide both sides by 4⁸

X = 4⁻⁹/4⁸

since the base is the same i.e the 4, you simplify the powers

Note: for division you subtract, for multiplication you add

X = 4⁽⁻⁹⁾⁻⁽⁸⁾

X = 4⁻⁹⁻⁸

X = 4⁻¹⁷
