Answer:
Step-by-step explanation:
The formula for simple interest is
prt = I, where p is the initial investment, r is the interest rate in decimal form, t is the time it's invested for, and I is the interest earned. We multiply the p, the r, and the t together to get I. For us that looks like this:
(2.58)(.05)(4) = I and
I = .516 or 52 cents.
4 and 2 since 6+2 is 8 and 8 has two factors which are 4 and 2.
I might be misreading something here but if:
x^5+243=0 subtract 243 from both sides
x^5=-243 raise both sides to the 1/5 power (or take the fifth root of both sides)
x=-3
So there is only one solution, x=-3
