It would be the first box, when multiplying exponents, you add the exponents and just keep the base. So it be 2^17
Answer:
x^8y^8
Step-by-step explanation:
(x^4y^3+1)^2
(x^4y^4)^2
Expand the bracket by multiplying the exponents by 2
x^8y^8
Cos^2 + cos^2 tan^2 (break the brackets)
Cos^2+ cos^2 • sin^2/cos^2 (divide out the cos^2)
Cos^2+ sin^2 (Cos2+ sin^2= 1)
= 1
Answer:
The quotient is 4x+5 and the remainder is -13
Step-by-step explanation:
Using synthetic division
-5 4 25 12
Bringing down the 4 and multiplying
-5 4 25 12
↓ -20 -25
----------------------
4 5 -13
The quotient is 4x+5 and the remainder is -13
Any number inside the modulus sign becomes positive. This means and so we have,
Solving these gives us
However if we check the second solution in the original equation we obtain . This is false and so can't be a solution.
Therefore the only solution is .
(Note: I'm not sure why the second solution didn't work but when there's a modulus sign involved it always pays to check your final answers to be sure. I'll have a think about it but in case you find out before I do, I'd be interested to know in the comments.)
