b^-3=1/216 b=?
743.8 × 103=?
36 ÷ 10–3=?
What is (2.1 × 103) × (4 × 10–7)?

Answers

-- A negative exponent means the number is in the denominator.
    b⁻³ means 1/b³ .
   So 1/b³ = 1/216 . You can do it now.

-- If that number is " 10³ ", it means 1,000 .
   If that number is " 103 " and you can't remember
   how to do multiplication with a pencil, then you'll
   have to use your calculator.

-- Again ... 10⁻³ means 1/10³ or 1/1000 .
   So the problem is really 36 divided by 1/1000 .
   Be very careful. That means 36 x 1000 .

-- To multiply powers that have the same base,
   you add the exponents.

   Example: 10⁴ times 10⁵ = 10⁹ .

   This question can be rearranged as (2.1 x 4) x (10³ x 10⁻⁷)

   (10³) times (10⁻⁷)   is 10⁻⁴ .

What what percent of 50 is 47

Answers

94%.
50 x 2 = 100
47 x 2 = 94

Percent means per hundred so you need to times 50 by whatever the number is that makes it 100. You need to do this on both sides so you do the same with the 47.

percent * whole = part
x * 50 = 47
/50 /50
x=0.94
0.94 = 94%
94% of 50 is 47
