if you need antilog(5), use \(10^5 = 100,000\)

if you are calculating in base 10.

If you are calculating in base e, use \(e^5 \approx 148.413\)

Assuming that we can include "negative" primes :

-30 =   -2 x 3 x 5     .......notice that the minus could be applied to any of the three primes

Note....... apparently, there is some debate whether or not primes can be negative!!!

This resource says one thing :  https://primes.utm.edu/notes/faq/negative_primes.html

This says another : http://mathforum.org/library/drmath/view/55940.html

I'm not well-versed enough in mathematics to referee this debate  !!!!!

Example

7 ^3+1/4   = 

7 ^13/4  =

[7^13] ^1/4  =

[ 96889010407 ] ^1/4     ≈   557.916

Note that we also could have evaluated this as

[ 7^(1/4) ] ¹³       ........the answers would have been the same

see my answer, here :  http://web2.0calc.com/questions/6r-5-s-3-3r-2-s-6-please-help#r1

I assume this is :

(2.83 – 4.17)²+(-3.17 – 4.17)²+(-.17 –4.17)² +(-1.17 –4.17)² +(-2.17 –4.17)² +(3.83 – 4.17)² 

(-1.34)^2 + ( - 7.34)^2 + (-4.34)^2   + (-5.34)^2 +  (-6.34)^2  + (-0.34)^2  =

1.7956    + 53.8756   + 18.8356 +  28.5156 + 40.1956 + 0.1156   = 143.3336

2x+1+5x = 9x+5       => 2x + 1 + 5x -9x = 5

                                => 2x + 5x - 9x  = 5 - 1

                                => -2x = 4

                               => x = 4/(-2)

                                => x = -2

who knows how to do irrational numbers and adding,subtracting,and multiplying irrational numbers if u do please help me with math cause for me 8th grade math is hard

a⁹ = 40*(1/4)⁸ 

a⁹  = 40 * [1/ 65536}

a⁹  = 40/65536

a⁹ = 5/8192        take the 9th root of both sides

a = [ 5 / 8192]^1/9   ≈  0 .43938

Evie.......isn't there supposed to be an "x" somewhere in the original problem  ????

3^(x+1)=4^(x-1)      take the log of both sides

log 3 ^(x + 1)  = log 4^(x - 1)   and we can write

(x + 1) log 3   = (x - 1)log 4     simplify

x log 3 + log 3 =  xlog 4 - log 4        rearrange

x log 3 - x log 4 =   - log 3 - log 4         multiply through by  -1

xlog 4 - x log 3 = log 4 +  log 3      factor out x

x [ log 4 - log 3 ]   = log 4 + log 3          divide both sides by [ log 4 - log 3]

x =  [ log 4 + log 3 ] / [ log 4 - log 3]  ≈  8.6377

538.333333333

A=πr^2

Max.....I assume you want this in terms of x and y instead of a and b

x = log₂ 3        y = log₃ 7    log₄₂ 56         use the change of base rule to write :

x = log 3 / log 2  →   log 2  =  log 3/ x

y =  log 7 / log 3   →  log 7  = y log 3      

log₄₂ 56   =    log 56 / log 42        and we can write this as :

log ( 2^3 * 7 )  / log ( 2 * 7 * 3)   =

[log2^3 + log 7] / [ log 2 + log 7 +  log 3]  =

[3 log 2 + y log 3 ]  / [  log3 / x + y log 3 + log 3]  

[ 3 * (log 3)/x + y log 3 ]  / [ log 3/x + ylog 3 + log 3]  =   [multiply top/bottom by x]

[ 3 log 3  + xylog3 ] / [ log 3 + xylog 3 + x log 3]  =      factor out log 3

 [ (log 3) ( 3 + xy ) ]  /  [ (log 3) [ 1 + xy + x ]   =       

[ 3 + xy ]  / [ 1 + xy + x ]

2-5 is -3

32/57 is the answer

A blimp can be seen flying at an altitude of

5800 feet above a motor speedway during a race. The slanted distance directly to the pagoda at the

startdash finish line is d feet. Express the horizontal distance h as a function of d.

What's the problem???

Convert the decimal into the simplest form of its equivilant fraction.

8/9(54x−36)+2=−3/4(−40+16x)+90x     distribute the two fractions over the terms in parentheses

48x - 32 + 2 = 30 - 12x + 90x       combine like terms

48x - 30  = 30 + 78x        ad 30 to both sides......subtract 78x from both sides

-30x  = 60      divide both sides by -30

x = -2
