Step-by-step explanation:
Let √x - 1/√x = a
Squaring both the sides,
x + 1/x - 2 = a^2
Putting the value,
3–2√2 + 1/(3–2√2) - 2 = a^2
a^2 = 1 - 2√2 + 1/(3–2√2)
= [(3–2√2) (1–2√2) + 1] / 3–2√2
= {3 - 8√2 + 9} / 3–2√2
= [12 - 8√2] / 3–2√2
Rationalising both the sides
= {(12 - 8√2)(3+2√2)} ÷ (9–8)
= 36 + 24√2 - 24√2 + 16(2)
= 36 - 32
=> 4
a^2 = 4
a = √4
a = 2, -2
So,
√x - 1/√x = a = 2, -2.
The triangle angle sum theorem states that the 3 angles in the triangle must equal 180 degrees.
Look, Dav...
This is a simple ex of Pyth. Theorem
26^2=24^2 + (DB)^2
then: DB = 10
Answer:
12.6
Step-by-step explanation:
The question requires you to estimate the product of 0.12 * 105
12/100 * 105 ----multiply 12 and 105
12 * 105 = 1260
Divide the answer by 100
1260/100 = 12.6
