-- 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 .
Answer:
x<_2
Step-by-step explanation:
Its the second answer choice.
3x<_6
Divide 3 by both sides and you get the answer.
Answer:
1, 2.5 at the top and 50 at the bottom
Answer:
5 inches
Step-by-step explanation:
Since the length of the sides of a cube are all equal,
volume of cube
= side ×side ×side
= (side)³
125= (length of side)³
Cube root both sides:
Length of each edge
= 5 inches
