Solve for y, where y is a real number vy+4=9

Question

Algebra 2. Cube root of an integer. Find the value of Solve for y, where y is a real number. Solve for y, where y is a real number √y+4=9

Answer 1

For a square root:

 

√(y+4) = 9

 

(√(y+4))² = 9²

 

y + 4 = 81

 

y = 77

 

--------------------

 

For a cube root:

 

³√(y+4) = 9

(³√(y+4))³ = 9³

y + 4 = 729

 

y = 725
