what is the value of 8⅔
Answers
Answer:
If we want to convert a mixed number to an improper fraction, we can use a shortcut. You used the shortcut. Let's look closer at the shortcut.
8²/3
= ( 3•8 + 2)/3
= 26/3
We take the denominator 3 and multiply it with the integer 8 to get 24. Then add 2 to get 26. Then we place the 26 over the denominator 3 to get the improper fraction.
[By the way, to convert −823 to an improper fraction, we subtract:
[3∙(−8)−2]/3=−26/3 ]
However, what you wrote in your question is not mixed number conversion—it’s exponentiation. You're raising a number to a power.
You wrote (8^2/3). This expression means 8•8/3 = 64/3.
Did you mean to write the 2/3 as the exponent? If so, then 8^(2/3) is the correct form.
8²/3
You probably need to wrap the 2/3 in parentheses on your calculator, depending on your model.
Without a calculator, you can simplify the expression in the following way:
8²/3
[ 23=21∙13=2∙13 ]
= (82)13
= (64)13 ( cube root of 64)
= 4
