5^-2 = ___
1/25
Simplify: 5^216
5^216 is a huge number and cannot be simplified further without calculating it.
The answer is either
30^2
90^6
10^6
30^6
30^6
Solve: 3 (- x + 2) < 15
3(-x + 2) < 15
-3x + 6 < 15
-3x < 9
x > -3
Therefore, the solution is x > -3.
Evaluate: (-2 - 3)^3 + 3^-3 (- 4)
First, we need to simplify (-2 - 3)^3:
(-2 - 3)^3 = (-5)^3
(-5)^3 = -5 * -5 * -5
(-5)^3 = -125
Next, we simplify 3^-3:
3^-3 = 1/3^3
3^-3 = 1/27
Now, we substitute these values back into the original equation:
(-2 - 3)^3 + 3^-3(-4) = -125 + (1/27)(-4)
-125 + (1/27)(-4) = -125 - 4/27
-125 - 4/27 = -125 4/27
Therefore, the final result is -125 4/27.
