8 cubed in standard form and exponential form
masya89 [10]

Answer:

  • so 8 cubed (8 × 8 × 8) in standard form is:  512
  • so 8 cubed (8 × 8 × 8) in exponential form is: 8³

Step-by-step explanation:

As we know that

The cube of any given number is that number times itself.

For example, 8 cubed, denoted by 8³ is equal to 8 × 8 × 8.

An exponent basically indicates the number of times we must multiply the base number. For example, to compute 8³, we multiply 3 three times (8×8×8).

  • so 8 cubed (8 × 8 × 8) in standard form is:  512
  • so 8 cubed (8 × 8 × 8) in exponential form is: 8³

What is the total number of common tangents that can be drawn to the circles
tester [92]

Answer:

A. 0

Step-by-step explanation:

The circles are concentric. I.e there is no point where the circumferences of both circles ever touch each other. Hence there can be no tangent line possible that can be common to both circles at the same time.
