Answer:
work is pictured and shown
it would be 40.22 but it's a repeating decimal
Use pemdas, parenthesis, exponents, multiplication/division, addition/subtraction. thats the best way to explain how to do this.
√4=2, and √45=√(9*5)=√9 *√5=3√5
so you have 2/(3√5)
Multiply both top and bottom by √5 to eliminate the √ in the denominator:
(2√5)/15 is the final answer.
It has a constant variation of 1/2
