Step-by-step explanation:
I guess that means
1.05 / 2.1
or
1.05 ÷ 2.1
both mean the same thing.
so, let's look at
1.05 / 2.1
this is the same as
105/100 / 210/100 = (105×100) / (210×100) =
= (105×100) / (210×100) × (1/100 / 1/100)
as long as we multiply numerator (top) and denominator (bottom) always with the same thing, the general fraction or division is unchanged.
(105×100) / (210×100) × (1/100 / 1/100) =
= (105 × 100/100) / (210 × 100/100) = 105 / 210
so, yes, the division of 105 / 210 is the same as 1.05 / 2.1
Answer:
4
Step-by-step explanation:
To simplify
÷ 
Change division to multiplication and turn the second fraction upside down, that is
× 
Cancel the factor (x + 3) on the numerator/ denominator , leaving
= 4
Answer:
B
Step-by-step explanation:
(x⁴ + x)^½
As x approaches infinity, x⁴ becomes much larger than x. So:
(x⁴ + x)^½ ≈ (x⁴)^½ = x²
So x² grows at the same rate as (x⁴ + x)^½.
I'm pretty sure it should be the 45. or A
