N = x4
x8 = x4+4 = (x4)2 = N2
It cannot be done because the base for the second log is not given.

1/x = 1/y + 1/zx = ( yz ) / (y + z)
-9-7x=-5 express first the equation in terms of x, where, 7x=-9+5 then, 7x=-4 thus, x=-4/7
x + 5y = 0 so x = -5y or y = -x/5 You can express x in terms of y or y in terms of x but it is not possible to solve a single linear equation in two variables.
It cannot be done because the base for the second log is not given.
Sin p is a ratio and so a number: it cannot have units such as degrees. As a result, the question is meaningless and so cannot be answered.
The circumference is 4pi
Yes. I = P/E which says current (I) equals power (P) divided by voltage (E). We normally see PIE, which is P=I x E or power equals current times voltage. If we divide both sides by E, we'll isolate I and express it in terms of P and E, as shown. The "PIE" thing is a nemonic (memory aid) to help you recall the formula.

You can combine like terms of p to get 6p. If you are given what p equals you can solve for the completely numerical answer.
Identity property of multiplication: States that when a given number is muliplied by one (fraction that equals 1) the result equals the given number.By reducing them to their lowest terms by means of their greatest common factors.
One linear equation in two variables cannot be solved. You can only express one of the variables in terms of the other.
1/x = 1/y + 1/zx = ( yz ) / (y + z)
terms are spelled out clearly for both terms
it states the power and energy of a given signal in terms of frequency
2x - 3y = 4This can't be solved, although you can express each variable in terms of the other.x = (4-3y)/2y = (2x-4)/3
