Simplify the expression.

Please add an explanation if you understand how to do this.

2x³¹

Step-by-step explanation:

(x¹⁶ + x⁴x¹²)x⁹x⁴/x⁻² =(x¹⁶ + x¹⁶)x¹³x² = 2x¹⁶x¹⁵ =2x³¹

Used identities:

nᵃnᵇ = nᵃ⁺ᵇ1/n⁻ᵃ = nᵃ

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
