Answer:
a²/9
Step-by-step explanation:
(27a⁻³) (-⅔) = 27^(-⅔) × (a⁻³)^(-⅔)
= (3³)^(-⅔) × a²
= 3⁻²a²
= a²/9
Answer:
Graph B shows function f of x equals 4 multiplied by 3 to the power of negative x.
Step-by-step explanation:
is the value 4 times three raised to the negative x. Graph B is the best representation.
Answer:
x = 4.6439
Step-by-step explanation:
2^x =25
Take the log of each side
log 2^x = log 25
We know that log a^b = b log a
x log 2 = log 25
Divide each side by log 2
x = log 25 / log 2
x =4.643856
Rounding to 4 decimal places
x = 4.6439
