Answer:
Step-by-step explanation:
Answer:
The answer is the last one (32x^7y^15)
You can bring x to the second power (x^2) because (x) is basically x^1. This is a basic exponent rule. (x^m)^n = x^m times n.
Then you can apply this rule to (2xy^3)^5. First you bring two to the fifth power and get 32. Then you bring x^5 according to the rule. Then you bring y^15, also because of the rule.
Now you have:
x^2 times 32x^5y^15
Now you just multiply the like terms together (x^2 and x^5)
When you multiply two exponents with the same base, you add the exponents together: a^n times a^m = a^n+m.
So you end up with 32x^7y^15
The number is 200 .
10 is 5% of 200
$3.48 with 8% tax would be 28 cents
God I remember when I had to that last year in 7th grade honors. I know you have to set up a proportion.
25/6. X/4. Find x and you get your answer
