Which is the simplest radical form of √52?

Mathematics
1 answer:
Zielflug [23.3K]3 years ago
4 0
Short answer: 2 * sqrt(13)
Remark
There are a number of ways to look at this. I'll pick the easiest.

Step one
Factor 52 until there are no more prime factors to be used.

52 = 2 * 26
52 = 2 * 2 * 13. That's as far as you can go.

Rule
For every 2 equal prime factors, 1 of them can be taken out side of the root sign. The other one disappears.

sqrt(52) = sqrt(2*2* 13) = 2*sqrt(13)

Answer 2sqrt(13) <<<< answer

Answer:

Option C.

Step-by-step explanation:

\sf\:x^{2}-3x+7=0

Use the biquadratic formula.

\sf\:\x=\frac{-\left(-3\right)(+/-)\sqrt{\left(-3\right)^{2}-4\times 7}}{2}

\sf\:x=\frac{-\left(-3\right)(+/-)\sqrt{9-4\times 7}}{2}

\sf\:x=\frac{-\left(-3\right)(+/-)\sqrt{9-28}}{2}

\sf\:x=\frac{-\left(-3\right)(+/-)\sqrt{-19}}{2}

\sf\:x=\frac{3(+/-)\sqrt{19}}{2}

Positive sign:

\boxed{\sf\:x=\frac{3+\sqrt{19}}{2}}

Negative sign:

\boxed{\sf\:x=\frac{3-\sqrt{19}}{2}}

Hope it helps ⚜

Your grandmother always has a jar of cookies on her counter. One day while you are visiting, you eat 5 cookies from the jar. In
stepan [7]

Answer:

b - 5 = c

Step-by-step explanation:

if you take the number of cookies before the visit (B) and then you eat 5, that would be (B - 5). after you eat the cookies, C is the amount left. so it’s a subtraction problem without 2 numbers. so the equation would be

b - 5 = c

or

before - 5 = after

Solving Exponential and Logarithmic Equations In Exercise, solve for x.<br> 500(1.075)120x = 100.000
Volgvan

Answer:

The solution is:

x = 0.61

Step-by-step explanation:

The first step to solve this equation is placing everything with the exponential to one side of the equality, and everything without the exponential to the other side. So

500(1.075)^{120x} = 100000

(1.075)^{120x} = \frac{100000}{500}

(1.075)^{120x} = 200

To find x, we have to apply log to both sides of the equality.

We also have that:

\log{a^{x}} = x\log{a}

So

\log{(1.075)^{120x}} = \log{200}

120x\log{1.075} = 2.30

120x*0.03 = 2.30

3.77x = 2.30

x = \frac{2.30}{3.77}

x = 0.61
