Answer:
translation to what language?
Step-by-step explanation:
2 × 2 = 4 ;
x^9 × x^4 = x^13 ;
y^7 = y^7 ;
z × z^3 = z^4 ;
<span>(2x^9y^7z)(2x^4z^3)
=4x^13y^7z^4 ;</span>
Answer:
15*20=300
15*16=240
20*57=1140
300+240+1140=<u><em>1680cm squared</em></u>
We can not evaluate it with real numbers, because there is no real number that multiplies itself twice and gives -25.
The answer is an imaginary number.
√-25 = 5i where i = √-1
So it can only be computed using imaginary numbers.
