Step-by-step explanation:
first do prime factorization of 324= 2×2×3×3×3×3
= 2 square, 3 square,3 square
therefore 324 is a perfect square
Now,
prime factorization of 588=2×2×3×7×7
= 2 square,7 square ,3
therefore 588 is not a perfect square
Answer:
Formula used :
hi
x=23.5
90=25-x/2+18
combine like terms
90=43-x/2
subtract 43 from both sides
47= -×/2
47/2= 23.5
or
90-25= 65
65-18=47
47/2=23.5
x = -3
(x - 2)^3 + 13 = -112
Subtract 13 from both sides
(x - 2)^3 = -125
Take the cube root of both sides
x - 2 = -5
Add 2 to both sides
