Answer:
<h3>-42</h3>
Step-by-step explanation:
given the expression;
(2+√-25)(4-√-100)
Note that √-25 = √-1 * √25
√-100 = √-1 * √100
According to complex number, √-1 = i
√-25 = 5i
√-100 = 10i
The expression becomes
(2+5i)(4-10i)
Open the parentehsis;
= 2(4)-20i+20i-50i²
= 8-50i²
Since i² = -1
The expression becomes;
8-50i² = 8-50(-1)²
8-50i² = 8-50 = -42
Hence the product of the expression is -42
Answer:
x=3130/3
Step-by-step explanation:
3,125 = 5-10 + 3x
5-10+3x=3125
3x-5=3125
3x-5+5=3125+5
3x=3130
3x/3 = 3130/3
x=3130/3
I hope this helps!
00 o = 2 1/2
— 00 o
2 — = 1 — = .25
2 2
00=2
o=1/2
2/2=1
.5/2=.25
Final answer = 1.25 or 1 1/4
