Find the roots
h1=0,h2=33210
Alternative Form
h1=0,h2≈1.981307
Evaluate
h4×9−70h
To find the roots of the expression,set the expression equal to 0
h4×9−70h=0
Use the commutative property to reorder the terms
9h4−70h=0
Factor the expression
h(9h3−70)=0
Separate the equation into 2 possible cases
h=09h3−70=0
Solve the equation
More Steps
Evaluate
9h3−70=0
Move the constant to the right-hand side and change its sign
9h3=0+70
Removing 0 doesn't change the value,so remove it from the expression
9h3=70
Divide both sides
99h3=970
Divide the numbers
h3=970
Take the 3-th root on both sides of the equation
3h3=3970
