Answer:

125\sqrt[4]{8}

Explanation:

A number of the form

a^{\frac{m}{n}}

can be re-written in the radical form as follows:

\sqrt[n]{a^m}

In this problem, we have:

a = 1,250

m = 3

n = 4

So, if we apply the formula, we get

1,250^{\frac{3}{4}}=\sqrt[4]{(1,250)^3}

Then, we can rewrite 1250 as

1250 = 2\cdot 5^4

So we can rewrite the expression as

=\sqrt[4]{(2\cdot 5^4)^3}=5^3 \sqrt[4]{2^3}=125\sqrt[4]{8}

Answer: The value remains under the radical is 8.

Explanation:

Given that,

1250^{\frac{3}{4}}

We know that,

a^{\frac{x}{n}}=n\sqrt{a^x}

Here, n = integer number

n is greater than x.

a = real number

Therefore,

1250^{\frac{3}{4}}=\sqrt[4]{1250}^3

1250^{\frac{3}{4}}=\sqrt[4]{2.5^{4}}^3

1250^{\frac{3}{4}}=5^3\sqrt[4]{2}^3

1250^{\frac{3}{4}}=125\sqrt[4]{8}

Hence, The value remains under the radical is 8.

A 6 m/s vector pointing North is added to a 2 m/s vector pointing East. What are the magnitude and direction of the resultant?
irina [24]

Answer:

A + B = C      Ax = 2   Ay = 0    Bx = 0  By = 6

Ax + Bx = Cx = 2

Ay + By = Cy = 6

C = (2^2 + 6^2)^1/2 = 6.32

Tan Cy / Cx = 6 / 2 = 3

Cy at 71.6 deg

when mary took a cold thick-walled glass out of the refrigerator and placed it in boiling water, the glass cracked. Explain why
goldfiish [28.3K]
The outer surface of the glass expands faster than the inside surface since glass is a fairly good thermal insulator. The outer surface tries to expand without the inner surface doing so at the same time. This is the secret of Pyrex glass. It is more conductive to heat and the inner and outer surface expand (and contract) at the same time.
