Where is "x" in your equation?

Good answer, GenericUsernameHere....!!!

[ Could you show the steps to  your solution  ?? ]

It's in standard scientific notation exactly as you have it written,

(1.3x10^12), you cannot simplify it any further.

In computer language it's written like this: 1.3E+12, sometimes they use small e, like this: 1.3e+12,

Both, E and e, stand for "exponent" or "powers of 10"

 \(x=26/3\)

2p+5r=q for p     subtract 5r from both sides

2p = [q - 5r]     divide both sides by 2

p = [q - 5r] / 2

-10=y+z for x    . there's no x here  !!!!

a/b=c for b   multiply both sides by b

a = bc        divide both sides by c

a/c = b

h-4/j=k for j     subtract h from both sides

-4j  = k - h      divide both sides by -4

j = [k - h] / -4    =   [ h - k] / 4

d=rt for t

t = d/r

pv=nrt for t

t=pv/nr

a= fv-ov/t for ov

ov = t (fv-a)

c=wtc/1000 for w

Divide both sides by c

0=wt/1000

w=1000/t

5000/3 = about $1666.66

x⁴ = 2   take the positive and negative 4th roots

x = (plus/minus) ⁴root(2)

209100/204.(how do you answer this but wording form ?)

No prob.....!!!

9+10=19

Like this. "How do you word this problem?"

All whole numbers are rational

Not all real numbers are rational  ....."pi" is an example

Example of an imaginary number.......   sqrt(-36)  = 6i

^ Thanks a billion.

A long list of number's often compiled into 3.14159265 or less.

Imaginary numbers can be letters.

Sorry.....GenericUsernameHere.....I didn't see the "tilde"

This means "congruent"    ....in other words, the two things on either side of the congruency sign have the same size and shape......

2n² = -144     divide by 2 on both sides

n² = -72       take the positive and negative roots of both sides

n = (plus/minus)sqrt(-72)

n = (plus/munus)( 6i ) * sqrt(2) 

What"s the square root of 225,

It's=15

^   This can't be the reflexive property. The reflexive property uses an equal sign. (sorry if this seems rude)

This is known as the "reflexive" property

Divide both top and bottom by the same number, for example: 4/6. We divide both top and bottom numbers by 2, so have: 4/2=2 and 6/2=3, so our new fraction is: 2/3

(3.5 x 10^-4) x ( 2.1 x 10^6)

Your answer is:

735=7.35 X 10^2
