Why does a number with an exponent of zero equal one?

1 answer:

5 0

When we multiply or divide the same base with exponents we add or subtract, so for that to work the 0th power has to equal 1

Dafna11 [192]

The answer would be 93.8667 feet per second.

64 miles to feet is 337,920

1 hour = 3600 seconds.

337,920 ÷ 3600 = 93.8667

Draw a conclusion is the statement below always sometimes or never true give at least two examples to support your reasoning the

hodyreva [135]

It's sometimes true.

One example is the least common multiple of 2 and 3 is 6, which is their product.

But the product isn't always the answer because (example 2:) the least common multiple of 6 and 10 is 30 because 6*5=30 and 3*10=30, however 6*10 is 60.

Ergo, it is only sometimes true.

21) PLEASE HELP WITH QUESTION. WILL MARK BRAINLIEST + POINTS.

Suppose f(x) = ----------
sqrt(x)
8
What if we let x = 16 (just an example)? We'd get f(16) = ------------- = 2.
sqrt(16)

What if we let x = g(x) = 2x+4?

We'd get the following:

8
f(g(x)) = -------------- = y
sqrt(2x+4)

So...the correct answer is the fourth one.
