Question
Solve the equation
a1=0,a2=52325
Alternative Form
a1=0,a2≈1.169607
Evaluate
5a2=8a5
Cross multiply
a2×8=5a5
Simplify the equation
8a2=5a5
Add or subtract both sides
8a2−5a5=0
Factor the expression
a2(8−5a3)=0
Separate the equation into 2 possible cases
a2=08−5a3=0
The only way a power can be 0 is when the base equals 0
a=08−5a3=0
Solve the equation
More Steps

Evaluate
8−5a3=0
Move the constant to the right-hand side and change its sign
−5a3=0−8
Removing 0 doesn't change the value,so remove it from the expression
−5a3=−8
Change the signs on both sides of the equation
5a3=8
Divide both sides
55a3=58
Divide the numbers
a3=58
Take the 3-th root on both sides of the equation
3a3=358
