Burka [1]

Answer:

What is the answer for this Evaluate 3|-3|.
zhenek [66]

Answer: 9

Concept:

Here, we need to know the idea of absolute value.

The<u> absolute value</u> of a number or integer is the actual distance of the integer from zero, in a number line.

There are <u>no negatives </u>in absolute value. So in practice "absolute value" means to remove any negative sign in front of a number, and to think of all numbers as positive.

Solve:

<u>Given</u>

3 |-3|

<u>Expand absolute value sign, which means making [-3] positive</u>

= 3 × (3)

<u>Simplify by multiplication</u>

= \boxed{9}

Hope this helps!! :)

Please let me know if you have any questions

What is (99/100)^101 times (100/99)^100?
sineoko [7]

Answer:

99/100

Step-by-step explanation:

First of all recall that

a^n\cdot b^n =(ab)^n

Now we we will try to apply that formula for a=99/100 and b=100/99.

First rewrite (99/100)^{101}=(99/100)\times (99/100)^{100}

Now

(99/100)\times (99/100)^{100}\times (100/99)^{100}\\=(99/100)\times ((99/100)\times (100/99))^{100}\\=(99/100)\times 1^{100}\\=(99/100)\times 1\\=99/100
