Answer:
The square root of 49 is rational
Step-by-step explanation:
If we take the square root of 49, we get 7, which is a rational number.
= (5a²)³ - 4³
you can apply the cubic factorisation rule
(a³ - b³) = (a - b)(a² - ab + b²)
= [5a² - 4][ (5a²)² - 20a² + 16]
= [5a² - 4][25a⁴ - 20a² +16]
I think this is it.
hope it helps.

Hi there! In order to find the simple interest rate of the bonds, we have to divide the received payment by the bonds invested in them. 504/8,000 is 0.063.
