Credible would be
Someone who's credible is honest and believable. ... Similar to words like reliable and plausible, credible is an adjective that comes to us from the Latin credibilis, meaning “worthy to be believed.” A credible reputation is often earned through consistent good behavior and an overall trustworthy personality.
The power (or exponent) of a number says how many times to use the number in a multiplication.
It is written as a small number to the right and above the base number.
In this example the little "2" says to use 8 two times in a multiplication:
82 = 8 × 8 = 64
But power can also mean the result of using an exponent, so in the previous example "64" is also called the power.
Another example: 24 = 2 × 2 × 2 × 2 = 16
• the power is 4: "2 to the power 4 is 16"
• or we can say the power is the result of 16: "the 4th power of 2 is 16"
