If <em>x</em> = -1, you have
2(-1) + 3 cos(-1) + <em>e</em> ⁻¹ ≈ -0.0112136 < 0
and if <em>x</em> = 0, you have
2(0) + 3 cos(0) + <em>e</em> ⁰ = 4 > 0
The function <em>f(x)</em> = 2<em>x</em> + 3 cos(<em>x</em>) + <em>eˣ</em> is continuous over the real numbers, so the intermediate value theorem applies, and it says that there is some -1 < <em>c</em> < 0 such that <em>f(c)</em> = 0.
Yea i gusse is this a question????????????????????????????????????????????????????????????..............................................................
Answer
(5)(1)3=53(
Step-by-step explanation:
Write both sides as powers of 8, then simplify:
However, on the left hand side, this would mean we'd have, 
, which is undefined (assuming the real-valued logarithm), so this equation has no real solution.
