Answer:
4²¹/5⁶ or 4398046511104/15625
Step-by-step explanation:
Remember, when raising a term with an exponent to some power, you must multiply the powers.

Answer:
s ≤ -18
Step-by-step explanation:
Multiply both sides of the inequality by -3. Since the multiplier is negative, you need to reverse the comparison symbol.
(-3)(-s/3) ≤ (-3)(6)
s ≤ -18
_____
If you multiply by a positive number, you don't need to reverse the symbol. Hence multiplying by 3 gives ...
-s ≥ 18
You can now add s to both sides:
0 ≥ 18 + s
and subtract 18 from both sides:
-18 ≥ s
Of course, this is the same relationship as ...
s ≤ -18
Answer:
x = -16
Step-by-step explanation:
-4x - 13 = 51
-4x = 51 + 13
-4x = 64
x = -16
