4ˣ⁻¹ = 49 / 4
<h3>How to simplify an expression?</h3>
The expressions can be simplified as follows;

Hence,

Therefore,

Finally,


2ˣ = 7
4ˣ⁻¹ = 2²⁽ˣ⁻¹⁾ = 2²ˣ ⁻ ² = 2²ˣ / 2² = (2ˣ)² / 2²
Therefore,
(2ˣ)² / 2² = 7² / 2² = 49 / 4
Hence,
4ˣ⁻¹ = 49 / 4
Finally, the
is equal to
and for the second part 4ˣ⁻¹ = 49 / 4

Answer:
3 + 5i
Step-by-step explanation:
Given
- 2i + (9 - 3i) - (6 - 10i) ← distribute parenthesis
= - 2i + 9 - 3i - 6 + 10i ← collect like terms
= 3 + 5i

Answer:
2255.31 cu.m
Step-by-step explanation:
Volume of a cylinder = πr²h
Given radius r = 6.5m
Height h = 17m
Volume = π × 6.5²×17
Volume = 3.14×6.5²×17
Volume of the cylinder = 2255.31cu.m
