Answer:
x = 2√7
using Pythagoras theorem:
For the bottom part:
Answer:

Step-by-step explanation:
Start by simplifying the denominator of the fraction. When multiplying exponents of the same base, you can add the exponents. This is also known as the product rule.

["a" is the base, and "x" and "y" are the exponents]
Using this we find...

When dividing exponents of the same base, you can subtract the exponents. This is also knows as the quotient rule.

Using this we find...

The answer is going 5 - 2x = 3
