X = 2i, -2i (I’m sorry if it does come back as wrong but it’s the only answer I got)
It is more effective if I explain using examples. So, for multiplication, you just have to multiply the magnitude, then add the exponents of the base 10. For example, when you multiply 5.2×10³ and 1.6×10², the solution would be:
(5.2)(1.6)(10³⁺²) = 8.32×10⁵
Now, for division, you will have to divide the magnitudes, and subtract the exponents by numerator minus denominator. The solution is as follows:
(5.2/1.6)(10³⁻²) = 3.25×10¹
Answer:
X = 4
Step-by-step explanation:
3x=16-4
3x= 12
X=12/3
X= 4
Answer:
40 degrees
Step-by-step explanation:
2x-30+x=90
Then you add x to 2x which will be 3x so now its
3x-30=90
add 30 to both sides
3x=120
divide 3 from both sides
x=40
Since Angle QPR is virticle to 2x-30+x=90
Angle QPR is 40 degrees
