Answer:
x=2 2/3
Step-by-step explanation:
The equation also means that x=8^3
8/3=2 2/3
Answer:
a(85) = -1033
Step-by-step explanation:
Explicit Arithmetic Sequence:
an = a1 + d(n-1)
d = -12 (by -37 + 25)
a(85) = -25 + -12(85-1)
a(85) = -1033
You apply the rule to put the exponent in front, and lower it by one. But since this is a nested expression, you apply it twice:
4*(5x^3-4)^3 * 3*5x^2 =
60x^2 (5x^3-4)^3
