Answer:
32
Step-by-step explanation:
If she started with 28, ad had 50 after she picked, you wold subtract 28 from 50 to find your answer.
Your calculator should give you the answer to both.
3^3 = 3 * 3 * 3 = 27
∛(125) = ∛(5 * 5 * 5) = Three equal factors under a cube root sign give 1 factor on the left of the cube root sign. The other 2 are discarded.
∛(5 * 5 * 5) = 5∛1 = 5
㏑(8^2) = ㏑(64)
or
㏑(a^n) = n㏑(a)
so
2㏑(8) = ㏑(64)
Is it what you mean by logarithmic equation ?
Answer:
3 ±i√39
------------
4
Step-by-step explanation:
The coefficients of this quadratic equation are a = 2, b = -3 and c = 6. Thus, the discriminant is b^2 - 4(a)(c), or (-3)^2 - 4(2)(6), or 9 - 48, or -39.
Thus, the roots are:
-(-3) ± i√39 3 ±i√39
x = ------------------- = ----------------
2(2) 4
This corresponds to the first of the four given answers.
