When 1,250^3/4 is written in simplest radical form, which value remains under the radical?

ddd [48]

Answer:

2 is inside the radical.

Step-by-step explanation:

We have to write the radical expression $1250^{3/4}$ in simplest form

Let us find the factors of 1250

$1250 = 2\times5^4$

Hence, we can rewrite the radical expression as

$(2\times5^4)^{3/4}$

Using the exponent rule $(x^a)^b=x^{ab}$

$(2^{3/4})\times(5^{4\cdot3/4})\\\\=2^{3/4}\times125$

Hence, we have 2 is inside the radical.

Answer:

42300000

Step-by-step explanation:

Use known fact

$1\ km=1000\ m$

Consider 1 square kilometer:

$1\ km^2=1\ km\times 1\ km=1000\ m\times 1000\ m=1000000\ m^2$

So, to find the answer, you have to multiply given number of square kilometers by 1000000:

$42.3\ km^2=42.3\times 1000000\ m^2=42300000\ m^2$

Rachel is using grouping to find the factors of a quadratic expression. She has reached the step shown below. Determine the fact

Feliz [49]

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

If the factored form is given by

$(3x-4)(x+2)$

Then its standard form will be given by

$(3x-4)(x+2)\\\\=3x^2+6x-4x+8\\\\=3x^2+2x+8$

if factored form is given by

$(3x+2)(x+4)$

Then its standard form will be given by

$(3x+2)(x+4)\\\\=3x^2+12x+2x+8\\\\=3x^2+14x+8$

Hence, only first option is correct.
