What Has The Same Value As Square Root Of 7 Multiply By Square Root Of 15

See if this works


=IF(J28<17,0,IF(J28<=25, J27*0.12, IF(J28<=30, J27*0.15, IF(J28<=35, J27*0.2, IF(J28<=40, J27*0.25, J27*0.3)))))


You may have to adjust for your boundary conditions. For example, if the value is 25, do you want to multiply by 12% or 15%?

Good luck,

Not enough information to answer. For AREA, you multiply length times width and get square feet. For VOLUME you multiply length times width times height and get cubic feet. You need a third value to calculate cubic feet.

Unfortunately this calculator does not display results in radical form. If you enter SQRT(147) you get 12.12435565...
What you are asking for is called rationalizing an irrational expression. Usually one tries to get rid of radicals that appear in the denominators. Here is an example.
Suppose you have 1/(c+SQRT(d)), and you want to get rid of the radical in the denominator. How to do it?
Recall the identity (a-b)*(a+b)= a^2-b^2. It is true for any a and b

Rationalizing a denominator (usual case)
Now consider (c+SQRT(d)). Multiply it by (c-SQRT(d))
[c+SQRT(d)]*[c-SQRT(d)]=c^2 -[SQRT(d)]^2=c^2-d
You see that there is no radical.
Now take 1/(c+SQRT(d)). To get rid of the radical from the denominator multiply it by (c-SQRT(d)). But to leave the value of your expression 1/(c+SQRT(d)) unchanged, you must multiply both numerator and denominator by (c-SQRT(d)).
The numerator becomes 1*(c-SQRT(d))=c-SQRT(d), and the denominator (c^2-d).
Finally, the rationalized form of the expression 1/(c+SQRT(d)) is
[c-SQRT(d)]/[c^2-d].

Rationalizing a numerator
Sometimes, people have a radical in the numerator that they want to get rid of and have it in the denominator. The procedure is the same
Example:(c+SQRT(d)), the denominator here is 1
(c+SQRT(d))=(c+SQRT(d))*[c-SQRT(d)]/[c-SQRT(d)]. This gives
[c^2-d]/[c-SQRT(d)]
You have no radical in the numerator but there is one in the denominator. This is called rationalizing the numerator.
Your case is a lot simpler
SQRT(147)=7*SQRT(3)
Multiply it by SQRT(3)/SQRT(3) which is 1. This gives
SQRT(147)=7*3/SQRT(3)=21/SQRT(3)

SQRT(147)= 21/SQRT(3)

in a 45-45-90 triangle, the lengths of the sides are in a ration, 1:1:√2, so if you have one side of the triangle, such as a leg, with the value in the ratio of 1, simply multiply that given number by √2 to get the hypotenuse, if you're instead given the hypotenuse, simply divide by √2 to get the answer for one of the legs. The legs of a 45-45-90 triangle are equal.
I hope this helps!

2ND [square-root] 2 0 =

The square-root is the shifted function of the multiply key. If the calculator shows you a symbolic result, press diamond ENTER to get a numeric result.

Are we discussing squares or square roots?

The square root is the 2nd function of the multiply key.

There is no square function on the keyboard. Instead, simply raise the number to the second power using the ^ key just above the divide.

the unit has a rating usually on the inside label ior the door somewhere...
you know the voltage allready... 120... multiply the 13 amps x the voltage... and presto 1560...
you can multiply that by .707 and get the RMS value... 1102

so I consider the microwave to be a 1000Watt unit... pretty easy... bu8t you wonder where did I get the numbers... like .707...
It's to compensate the peak to thr RMS... root mean square... lets just call it "Average"

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/lisa_52daba487e5b4d53

If you would like to a root other than a square root, first enter the root value (3, 4, 5, etc.) then press MATH. Then Press 5 and enter the value you want to take that root of. Press ENTER.

A squared + B squared = C squared
15 squared + 15 squared = C Squared
225 + 225 = c squared
450 = c squared
the square root of 450 is 21.21320433
