Answer:4

Step-by-step explanation:

log₂[log₂(√4x)] = 1

log₂2 =1

So we replace our 1 with log₂2

log₂[log₂(√4x)] = log₂2

log₂ on bothside will cancel each other.

We will be left with;

[log₂(√4x)] = 2

log = power of exponential

√4x = 2²

√4x = 4

Square bothside

(√4x)² = 4²

4X = 16

Divide bothside by 4

4x/4 = 16/4

x = 4

Your friend buys a skateboard that is on sale for one third off the original price. Your friend spent $36 than the original pric
White raven [17]

Answer:

original price of skateboard = $54

Step-by-step explanation:

Let the original price of the skateboard be x

selling price = one third off the original price = $36

x - (1/3x) = 36

\frac{x}{1} - \frac{x}{3} = \frac{3x-x}{3} = \frac{2x}{3}

\frac{2x}{3} = 36\\2x = 108\\x = \frac{108}{2} = 54

∴ x = 54
