tan(3) = x/10
x = 10 * tan(3)
x = 0.52407779283
It's just 1 divided by the variable/constant to the absolute value of the exponent
Example:
x^(-5) = 1/x^5
If the angles are congruent, then
7x+15 = 2x+12
5x = -3
x = -3/5
2^x = 6
Reversed, this equation becomes log with a base of 2 of 6 equals x.
so enter log2(6) into the calculator and you should get 2.58
First of all, -4 * 5 = -20.
Then, n^5 * n^7 = n^(5+7) = n^12
So the final answer is -20n^12
\(\frac{7.4*10^6}{6.8*10^-6} = \frac{7.4}{6.8}*\frac{10^6}{10^-6}\)
7.4 / 6.8 is approximately 1.088. This multiplied by the second part is 1.088 * 10^12. After rounding to 1 significant figure, you would get 1 * 10^12
27 = 9x
27/9 = 9x/9
x = 3
if you mean y = 3* (-2) - 2, then y = -8
but you mean y = 3* (-2)(-2), then y = 12
