Why is a number raised to the zero power ALWAYS one and never any other number?

Mathematics
1 answer:
alexdok [17]3 years ago

Do you know how to simplify, let's say for example,    x⁵/x²  ?

When the bases are the same, you can just subtract the exponent in
the denominator from the exponent in the numerator.  So  x⁵/x² = x³ .

Now look at  x⁷/x⁷ .  From that same handy tip, x⁷/x⁷ = x⁰ .

BUT ... any fraction with the same number on top and bottom
is equal to ' 1 '.  So  x⁰ = 1 , no matter what 'x' happens to be.

Does that do anything for you ?

A = 6 - 35 B = 3x + 53<br> Solve for x then find the measure of A.
11111nata11111 [884]

Answer:

A = 73°

Step-by-step explanation:

A + B = 180 because of alternating interior angles

Substitute each angle

6x - 35 + 3x + 53 = 180

9x + 18 = 180

9x = 162

x = 18

Substitute A

A = 6x - 35

A = 108 - 35

A = 73

Hope this helps

Have a great day!

Answer:

<em>a:b:c=8:12:15</em>

Step-by-step explanation:

<u>Combined Ratio</u>

We are given the ratios:

a:b=2:3

b:c=4:5

The combined ratio a:b:c will include all three variables in one single expression.

Before finding it, we must have a common number for the common variable (b). Since b is 3 in the first ratio and 4 in the second ratio, we must equate both by finding the LCM of 3 and 4=12, thus both ratios will be amplified as follows:

a:b=2:3=(2*4):(3*4)=8:12

b:c=4:5=(4*3):(5*3)=12:15

Now there is a common factor in both ratios, we can combine them removing the common factor:

a:b:c=8:12:15
