Convert 5 square root of a into exponential form?

stich3 [128]

Answer:

The answer is: " $5a^\frac{1}{2}$ " .

_____________________________________________

Step-by-step explanation:

______________________________________________

We are asked to convert "5 square root of a" ; into "exponential form".

Note that "5 square root of a" ;

or; " 5 root a " ;

means: " 5 times the {square root of the variable, "a" };

or : " 5 multiplied by the {square root of the variable, "a" }.

_______________________________________________

This can be written as: " $5\sqrt{a}$ " .

_______________________________________________

Note the following property of exponents:

$\sqrt[n]{a^m} = (\sqrt[n]{a})^m = a^m^n$ .

_____________________________________________

So; to write: " √a " ; as an exponent :

______________________________________________

Note:

" $\sqrt{a} = \sqrt[2]{a} = \sqrt[2]{a^1} = (\sqrt[2]{a})^1 = a^\frac{1}{2}$ " .

_______________________________________________

So:

" $\sqrt{a} = a^\frac{1}{2}$ " ;

_______________________________________________

And:

________________________________________________

" $5\sqrt{a} = 5a^\frac{1}{2}$ " .

________________________________________________

→ The answer is: " $5a^\frac{1}{2}$ " .

Kirsty counts the number of peas in a sample of pea pods

RoseWind [281]

Mode is most occurring

There is no mode for the peas as there is no score occurring more than once

Median is middle number

So cross of 4 and 5, and 7 and 8

Median is 6

Mean is average

4+5+6+7+8 divided by five

Mean is 6

Solve the following quadratic equation for all values of x in simplest form.

denis-greek [22]

Answer:

$x=\sqrt{7},\:x=-\sqrt{7}$

Step-by-step explanation:

Start by rewriting the equation to standard form $ax^2+bx+c=0$ .

$5(x^2-10)+5=-10,\\5x^2-50+5=-10,\\5x^2-35=0$ .

Factor out the 5, then isolate $x^2$ :

$5x^2-35=0,\\5(x^2-7)=0,\\x^2-7=0,\\x^2=7,\\x=\pm \sqrt{7}.$ .

Therefore, the solutions to this quadratic are:

$x=\sqrt{7},\:x=-\sqrt{7}$
