Answer: x = ± 1.68
Step-by-step explanation:
7x^4 = 56
x^4 = 56/7
x^4 = 8
Let a = x²
(x²)² = 8
(a)² = 8
a = ± √8
Now,
a = -√8
x² = -√8 has no real solution.
Taking +√8
a = √8
x² = √8
x = ± √(√8))
x = ± 1.68
Please give thanks and brainliest if correct!
Please include the instructions when you post a question. Thanks.
Use the formula A = P*e^(rt).
Here, A = $700*e^(0.065*t), where t is the # of years (which you have not yet included in your post).
As an example: After 2 years you'll have A = $700*e^(0.065*2), or A=$797.18, in your account.

It’s correct
you tell us, what would you end up multiplying 63.78 there, to get the 4 1/5% of it?
