Step-by-step explanation:
<h2>[1]</h2>Therefore principal is $500.
<h2>__________________</h2><h2>[2]</h2>Let the total number of balls be x.
→ Red balls + Blue balls + Yellow balls = Total number of balls
Total number of balls is 315.
A/Q,
3/5 of the balls are blue.
Answer:
256
Step-by-step explanation:
A calculator works well for this.
_____
None of the minus signs are subject to the exponents (because they are not in parentheses, as (-1)^5, for example. Since there are an even number of them in the product, their product is +1 and they can be ignored.
1 to any power is still 1, so the factors (1^n) can be ignored.
After you ignore all of the things that can be ignored, your problem simplifies to ...
(2^2)(2^-3)^-2
The rules of exponents applicable to this are ...
(a^b)^c = a^(b·c)
(a^b)(a^c) = a^(b+c)
Then your product simplifies to ...
(2^2)(2^((-3)(-2)) = (2^2)(2^6)
= 2^(2+6)
= 2^8 = 256
