3. Rationalize the denominator and simplify:2−1018
Multiply numerator and denominator by the conjugate of the denominator:
2−1018⋅2+102+10=(2−10)(2+10)18(2+10)
Simplify the denominator using the difference of squares:
(2−10)(2+10)=(2)2−(10)2=2−100=−98
Expand and simplify:
−9818(2+10)=−98182+180=98−182−180
Simplify further:
98−182−180=49−92−90
4. Rationalize the denominator and simplify:6−3y21y−252
Multiply numerator and denominator by the conjugate of the denominator:
6−3y21y−252⋅6+3y6+3y=(6−3y)(6+3y)(21y−252)(6+3y)
Simplify the denominator:
(6−3y)(6+3y)=62−(3y)2=36−3y
Expand the numerator:
(21y−252)(6+3y)=(21y⋅6+21y⋅3y)−(252⋅6+252⋅3y)=126y+21y3y−1512−2523y
Combine:
36−3y126y+21y3y−1512−2523y
This is the rationalized expression.
5. Rationalize the denominator and simplify:p−3p+183p2−14p−24
Multiply numerator and denominator by the conjugate of the denominator:
p−3p+183p2−14p−24⋅p+3p−18p+3p−18
Simplify the denominator:
(p−3p+18)(p+3p−18)=(p)2−(3p)2−(18)2=p2−3p−324
Expand the numerator:
(3p2−14p−24)(p+3p−18)
This requires detailed expansion, but the rationalized form will involve combining terms with radicals.
6. Rationalize the denominator and simplify:x+14−5x4−x2
Multiply numerator and denominator by the conjugate of the denominator:
x+14−5x4−x2⋅x−14−5xx−14−5x=(x+14−5x)(x−14−5x)(4−x2)(x−14−5x)
Simplify the denominator:
(x+14−5x)(x−14−5x)=x2−(14−5x)=x2−14+5x
Expand the numerator:
(4−x2)(x−14−5x)=(4−x2)x−(4−x2)14−5x=4x−x3−(4−x2)14−5x
This is the rationalized form.
