x = -21
how do I solve 1/2^30/17.5 on a calculator?
Let us make it clearer. Is it (1/2)^30 OR 1/(2^30)? And then you want to divide the result by 17.5? Let us know. Thanks.
Just enter it into the calculator just like you have it ........!!!!
7x^-8 x 6x^3 =
[ 7 * 6] * [ x-8 * x3] =
42x-5
x=1/2
x-2/3 = -1/6 add 2/3 to both sides
x = 2/3 - 1.6 [2/3 = 4/6]
x = 4/6 - 1/6
x = 3//6 = 1/2
Sine and Cosine of 45 are equal=1/sqrt(2), but
Sin^2 + Cos^2=1
Don't get confused, here.......cos(45) and sin(45) mean that we are finding the cosine and sine, respectively, of a 45 degree angle......they have the same value......we are not "multipying" the cosine and sine by 45.....!!!
Do you mean 10 X Log(19)=10 X 1.27875=12.7875
If you mean Log(19) to base 10 =1.27875 Take your pick!.
what is 8.424242... as a fraction in simplist form
hurry for pre S.A.T
=8 14/33=278/33
3.14....
it is irrational
that was just extra in-fo
Simplify: means make it simple or simpler.
now what does simplify mean????
An identity: An equation that is true no matter what values are chosen.
thanks
x = (ax-a+4)4 simplify
x = 4ax - 4a + 16
x - 16 = 4ax - 4a factor the rght side
x - 16 = (4a)(x - 1) divide both sides by 4(x - 1)
[(x - 16) / [(4(x -1)] = a
Means find the value of something or the answer to something.
5(2x-3)≥15x simplify the left side
10x - 15 ≥ 15x add 15 to both sides........subtract 15x from both sides
-5x ≥ 15 divide both sides by -5 and reverse the inequality sign
x [less than or equal to] -3
9 X 8 =72
54 = .67N divide both sides by ,67
54 / .67 = N = about 80.597
54 is 67% of what amount?
n.67=54
n=54/.67
n=80.60........but 54/.66666666666666667=81
81^(1/4)=3
It is this: (log(10))/(log(X))
