Question

Evaluate the given expressions. All numbers are approximate. 15.66^2-(-4.017)^4/1.044(-3.68)

Answer 1

you can use calculator for this problem, i think so.

Answer 2

what do u mean by evaluate...?
solve?

Answer 3

It just says to evaluate the expression and then solve them but keep in mind they are approximate

Answer 4

For some reason I'm not getting the right answer

Answer 5

what answer are you getting?

Answer 6

I got188.59

Answer 7

ok, I'm getting a different one, so lets take it line by line then

Answer 8

There is a certain way this has to be done but I don't know

Answer 9

top line : 15.66^2-(-4.017)^4
so start with the powers
15.66^2 = 245.2356
(-4.017)^4 = 260.3798

so 15.66^2-(-4.017)^4
= 245.2356 - 260.3798
= -15.14

so numerator reduces to -15.14
all good so far?

Answer 10

Oh okay I see

Answer 11

cools,
now bottom line (denominator) 1.044(-3.68)
= 1.044 times (-3.68)
= -3.842

Answer 12

so your final equation (which you can pop straight into a calculator) is
-15.14 / -3.842
= 15.14 / 3.842
=... ? @Ash90 ?

Answer 13

Yes I have the bottom correct -3.84192

Answer 14

damn, no i had it wrong

Answer 15

So my final answer should be 3.941

Answer 16

bottom = -3.84192 is correct

Answer 17

but the equation i think should be more like:

Answer 18

\[15.66^2-\frac{(-4.017)^4}{1.044 \times (-3.68)}\]

Answer 19

as there are no brackets around the 15 and the -4

Answer 20

sorry about that
so start with the fraction
(-4.017)^4 = 260.3798
over
1.044 times (-3.68)
= -3.842
so
260.3798/ -3.842
= -67.77

therefore: (remembering 15.66^2 = 245.2356)
15.66^2 - (-67.77)
= 245.2356 - (-67.77)
= 245.2356 + 67.77
= ...?

Answer 21

= the final answer ;D @Ash90

Answer 22

Okay thank you
