Answer:
At The given rate, the area of floor that Jessica can wax is 33.3 m²
Step-by-step explanation:
Given as :
The area of floor waxed = 20 square meters
The time taken to waxed 20 square meters floor = hours
Let The area of floor waxed per hour = A m²
<u>Now, Applying unitary method</u>
∵ In hours, The area of floor waxed = 20 m²
∴ In 1 hour , The area of floor waxed = m²
I.e In 1 hour , The area of floor waxed = m²
Or, In 1 hour , The area of floor waxed = = 33.3 m²
Or, In 1 hour The area of floor waxed = A = 33.3 m²
Hence, At The given rate, the area of floor that Jessica can wax is 33.3 m² Answer

<h3><u>Given</u><u>:</u><u>-</u></h3>
(√3+√2)/(√3-√2)
<h3><u>To </u><u>find</u><u>:</u><u>-</u></h3>
<u>Rationalised</u><u> form</u><u> </u><u>=</u><u> </u><u>?</u>
<h3><u>Solution</u><u>:</u><u>-</u></h3>
We have,
(√3+√2)/(√3-√2)
The denominator = √3-√2
The Rationalising factor of √3-√2 is √3+√2
On Rationalising the denominator then
=>[(√3+√2)/(√3-√2)]×[(√3+√2)/(√3+√2)]
=>[(√3+√2)(√3+√2)]×[(√3-√2)(√3+√2)]
=>(√3+√2)²/[(√3-√2)(√3+√2)]
=> (√3+√2)²/[(√3)²-(√2)²]
Since (a+b)(a-b) = a²-b²
Where , a = √3 and b = √2
=> (√3+√2)²/(3-2)
=> (√3-√2)²/1
=> (√3+√2)²
=> (√3)²+2(√3)(√2)+(√2)²
Since , (a+b)² = a²+2ab+b²
Where , a = √3 and b = √2
=> 3+2√6+2
=> 5+2√6
<h3><u>Answer:-</u></h3>
The rationalised form of (√3+√2)/(√3-√2) is 3+2√6+2.
<h3>
<u>Used formulae:-</u></h3>
→ (a+b)² = a²+2ab+b²
→ (a-b)² = a²-2ab+b²
→ (a+b)(a-b) = a²-b²
→ The Rationalising factor of √a-√b is √a+√b
