En las potencias con base 10, el resultado será la unidad seguida de tantos ceros como indica la cifra del exponente

radiacion

En matemáticas, la radicación es el proceso de hallar raíces de orden n de un número a.1.

De modo que se verifica que

x n = a {\displaystyle x^{n}=a}

, donde n es llamado índice u orden, a es llamado radicando, y x es una raíz enésima.23

La raíz de orden dos de

a {\displaystyle a}

, se llama raíz cuadrada de

a {\displaystyle a}

y se escribe como

a {\displaystyle {\sqrt {a}}}

o también

a 2 . {\displaystyle {\sqrt[{2}]{a}}.}

La raíz de orden tres de

a {\displaystyle a}

, se llama raíz cúbica de

a {\displaystyle a}

y se escribe como

a 3 . {\displaystyle {\sqrt[{3}]{a}}.}

Las raíces de órdenes superiores se nombran usando números ordinales, por ejemplo raíz cuarta o raíz séptima.

La radicación es la operación inversa a la potenciación. s:

What is the best approximation for the perimeter of a semicircle with a diameter of 35 inches?

Dafna11 [192]

Answer:

Circumference shares the same concept with perimeter.

First, let's use the formula for the circumference of a full circle.

C = 2πr

Where 'π' stands for pi(22/7 or 3.14) and 'r' stands for the radius.

C = πd

Where 'π' represents pi(22/7 or 3.14) and 'd' stands for the diameter.

But, we are trying to find a semi-circle's circumference. So, what you would do is that you would divide the whole product of the formula by 2.

For this, I'll be using this formula C = πd. Though, since we are dividing by 2 we can apply that to the diameter and make it a radius in our formula.

So the 'd' in the formula will be 'r'.

Now, let's find the radius.

D/2 = R

So,

35/2 = 17.5

Use this in our formula:-

C = πr

C = 3.14(17.5)

C = 54.95 inches.

8 2/5 - 5 3/5 need help solving step by step

Tpy6a [65]

Answer: 2 and 4/5

Explanation: To subtract mixed numbers, first subtract the fractions. Notice here however that we have 2/5 - 3/5 which will give us a negative fraction. Since this will cause us a lot of trouble, instead, let's rewrite the first mixed number.

We can do this by thinking of 8 and 2/5 as 7 + 1 and 2/5 or 7 + 7/5 by changing 1 and 2/5 to the improper fraction 7/5. So 8 and 2/5 can be written as 7 and 7/5.

So we have 7 and 7/5 - 5 and 3/5.

Now, subtract the fractions. So we have 7/5 - 3/5 which is 4/5. Then subtract the whole numbers so we have 8 - 5 which is 2.

2 and 4/5 is in lowest terms so 8 and 2/5 - 5 and 3/5 is 2 and 4/5.
