To solve the equation x^2 + 4x = 5, we first need to rewrite it in standard form by combining like terms: x^2 + 4x - 5 = 0. Next, we can solve for x by factoring the quadratic equation or using the quadratic formula. Factoring may involve trial and error or the use of the AC method. Alternatively, the quadratic formula, x = (-b ± √(b^2 - 4ac)) / 2a, can be used where a = 1, b = 4, and c = -5 in this case.

XXXX = X to the fourth power.
Factor out X squared, and you'll get (X squared)(1 + X squared) = 5.
Then set each one equal to five and you'll get two s.
(X squared) = 5, so X = 2.236. (1+X squared) = 5, so X = 2.
AnotherBut if you substitute x=2 into the expression x2+x4=5 you get 4+16=5.If the expression is intended to be x2+4x-5=0 then x=1 and x=25 are solutions Make the substitution y=x2, The equation can then be written as y2+y-5=0. You can then complete the square or apply the quadratic formula. y=[-b+√(b2-4ac)]/2 where a=1, b=1, and c=-5 which upon substitution for a, b, and c becomes
y=[-1+√21]/2=1.791287847=x2; x4=y2=3.208712153 and x2+x4=5
The sum of four and the product of three and a number xxxx.
A London (UK) phone number has 8 digits. If you wish to dial a London (UK) phone number from outside the London area (or a mobile phone) you need to prefix the 8 digits by the 3 digit London area code of 020 (which would normally be displayed in brackets before the number viz: (020) yxxx xxxx - the y is either 3, 7 or 8). If you wish to dial it from outside the UK, you'll need the international prefix for your country, followed by the country code of 44 plus the London area code without the leading zero plus the 8 digits, ie: +44 20 yxxx xxxx
In excel cell, type =ABS(XXXX). It will return the absolute value of the number or equation you put within the parentheses.
If xxxx is meant to represent a series of multiplications, and the "and" between 81xxxxxxx and 32yyyy implies addition, then the answer is sqrt(81x7 + 32y4) which cannot be simplified to any significant degree. If the "and" imples multiplication, then sqrt(81x7 * 32y4) = 36x3y2*sqrt(2x)
There are a lot of models to the scientific calcuator and I don't know if they all work the same. On the more standard versions, you can generate a uniform random deviate, from 0 to 0.999 by pressing shift Ran# = . I have included a general link, but if it doesn't work, then you can do a search under casio calculator manual model number xxxx, and download a users manual. Good luck.
