Why do square roots have to be represented as fractional exponents?

1 answer:

7 0

Fractional exponents make square roots easier to simplify. For example, the square root of 1681 isn't obvious. But if you used fractional exponents and prime factorization, you would get 41.

$\sqrt{1681} = 1681^{1/2} = (41^2)^{1/2}= 41^1 = 41$

Use the Pythagorean Theorem to find the distance to the nearest tenth, between F(9, 5) and G(-2, 2). (Hint: Place F and G on the

artcher [175]

Put a point H on (9, 2). Sketch a triangle out of the three points. Distance between (-2, 2) and (9, 2) is going to be 11. Distance between (9, 2) and (9, 5) is going to be 3. These correspond to the a and b of the Pythagorean Theorem
c^2=a^2+b^2
c=√11^2+3^2=√130
Square root of 130 is 11.4

Answer:

B. 2 (Second Option)

Step-by-step explanation:

Four times: ⇒ 4
