3^4 can be written as:
3 to the power of 4.
3 is the base number, and 4 is the exponent.
An exponent is basically a summarized version of saying the base number multiplies against itself however many times, the exponent clarifies that.
So... we'd write it out as:
3^4 = 3 * 3 * 3 * 3
In the end we get:
3 * 3 = 9, 9 * 3 = 27, 27 * 3 = 81
3^4 = 81 | There's your conclusion.
I hope this helps, have a great rest of your day! ^ ^

Answer:
8.1192
you need to multiply the decimal to the grand number:
0.08 x 101.49 = 8.1192
We need to set up an equation to solve this problem. The sales tax is a percentage of the total, so that's what we are looking for.
Let's call S our sales tax
So, that's what we are looking for, and we are given the actual sales tax
So now we have a decimal. In order to convert a decimal into a percentage, we must multiply by 100 (since percentages are out of 100)
The sales tax rate is 3.8%
Answer:
9/10
Step-by-step explanation:
If you are truly "struggling," you might want to consider working the problem using your calculator. It will give you a decimal answer: 0.9.
You know this is nine tenths, or 9/10 when written as a fraction.

When adding fractions, you are instructed to use a common denominator. Usually, that instruction is to find the "least" common denominator. In many cases, that simplifies reducing the fraction that will be the answer.
However, <em>any</em> common denominator will do. The easiest one to find is the product of the denominators. Here, that is 2·5 = 10.
The first fraction has a denominator of 2, so to make its denominator 10, you need to multiply it by 5/5.
The second fraction has a denominator of 5, so to make its denominator 10, you need to multiply it by 2/2.
__
Effectively, we have used the formula for the sum of two fractions:
(a/b) +(c/d) = (ad +bc)/(bd)
1/2 + 2/5 = (1·5 +2·2)/(2·5) = 9/10
3x60= 180 2×80=160 so the flour will outweigh the sugar
