Evaluate the following expression. 5^-3

Mathematics
1 answer:
Ulleksa [173]3 years ago
6 0
5^-3 is 1/125

The negative in the exponent makes it so there is a 1 over the problem if there was no negative. When you have a negative in the exponent, the answer will be the reciprocal (opposite) of the question with no negative.
For example,

9^2 = 81

9^-2 = 1/81

-75/8 -71/88 which is greater
Setler79 [48]
Trick question. See these negative signs? The left number is -9.375, and the right number is -0.8068181818181818...  Notice that even though the right number looks like a smaller answer, it is closer to 0 on a number line, because it is negative. -71/88 is the correct answer.

A restaurant bill is $84.96. Estimate a 20% tip. Estimate a 15% tip.
Lisa [10]
If you have to estimate I will put $85 and then to find 20 % you just have to kniw that 10% is equal to 8.5 you just move a decimal then you just add 8.5 plus 8.5 = 17 so 20% of 85 is equal to $17 and to find 15% you already know how much is 10%=8.5 so you just need to find 5% that is equal to 4.25 and then you just add 4.25 to 8.5 and that's equal to 12.75

20%= 17
15%=12.5
