x8+9=81 -9 -9 x8 =72 /8 /8 x= 9
If x = 8 and y = 10 then it is 44.
No.
2x8(x8) = (2)(x8)(x8) = 2(x8+8) = 2(x16) = 2x16
64
36
I'll assume you mean x6 + x8 + x3 Note if this is what you want to ask, then the best way to type it where you have no formatting capabilities would be:x^6 + x^8 + x^3 (the carat '^' symbol means 'raise to the power of')So the highest power of x is 8.
-1
X -8 same as, 1/X8 ====
8 x 0.25 = 2
By using the basic rules of exponents, plus the fact that the exponential function (e raised to some power) and the natural logarithm are inverse functions. e8 ln x + cos x = e8 ln x ecosx = e(ln x)(8) ecosx = (eln x)8 ecosx = (eln x)8 ecosx = x8 ecosx
30 x 8 = 240
