Solve by factoring and i need the steps too !!

IrinaVladis [17]

Answer:

$x_1 = -8\\\\x_2 = 8$

Step-by-step explanation:

To solve this problem use the formula "Difference of squares":

$(a + b) (a-b) = a ^2 -b ^ 2$

In this problem we have the following equation

$x ^ 2 -64 = 0$

This we can write it in the following way

$x ^ 2 - 8 ^ 2 = 0$

Then if a = x and b = 8 then:

$x ^ 2 - 8 ^ 2 = (x+8)(x-8) = 0$

Then the product of both factors is equal to zero when:

$x+8 = 0\\\\x =-8$

$x -8 = 0\\\\x =8$

The cube root of 0.000004913 is

Vlad1618 [11]

Answer:

$\sqrt[3]{0.000004913}=0.017$

Step-by-step explanation:

Cubic Root

The cubic root of a number N is M, if

$M^3=N$

It's usually tedious to manually compute cubic roots, but if we use some basic algebra concepts, the job is easily done.

Let's compute

$M=\sqrt[3]{0.000004913}$

The argument can be expressed in scientific notation as

$0.000004913= 4913\ 10^{-9}$

The power of 10 has an exact cubic root since the exponent is a multiple of 3. To find the cubic root of the mantissa, we note it's the triple product of 17, i.e.

$4913=17*17*17=17^3$

Thus our number is

$M=\sqrt[3]{17^3\ 10^{-9}}=17\ 10^{-3}=0.017$

We have then

$\boxed{\sqrt[3]{0.000004913}=0.017}$
