Show how to multiply 6 x 298 using friendly numbers and then use properties and mental math.

Black_prince [1.1K]

For this case we have the following multiplication:

$6 * 298$

We can rewrite this operation to facilitate the calculation.

We have then:

$6 * 298 = 6 * (200 + 90 + 8)$

From here, we apply the distributive property.

We have then:

$6 * 200 + 6 * 90 + 6 * 8$

Rewriting we have:

$1200 + 540 + 48$

Finally adding all the numbers we have:

$1200 + 540 + 48 = 1788$

Answer:

The value of 6 * 298 is 1788 and the calculations can be provided as follows:

$6 * 298 = 6 * (200 + 90 + 8)$

Solve the equation:

PilotLPTM [1.2K]

Answer:

Step-by-step explanation:

$4\sqrt{3-\frac{1}{x} } -\sqrt{\frac{x}{3x-1} } =3\\4\sqrt{\frac{3x-1}{x} } -\sqrt{\frac{x}{3x-1} } =3\\\\put ~\sqrt{\frac{3x-1}{x}} =a\\4a-\frac{1}{a} =3\\4a^2-1-3a=0\\4a^2-4a+1a-1=0\\4a(a-1)+1(a-1)=0\\(a-1)(4a+1)=0\\a=1,-\frac{1}{4}\\$

$\sqrt{\frac{3x-1}{x} } =1\\3x-1=x\\3x-x=1\\2x=1\\x=\frac{1}{2}$

when a=-1/4

$\sqrt{\frac{3x-1}{x} } =-\frac{1}{4} \\$

$\frac{3x-1}{x} =\frac{1}{16} \\48x-16=x\\47x=16\\x=\frac{16}{47}$
