Answer:
≈ 3.6 x 10^1
Step-by-step explanation:
= (6.05 x 3.05) x 10^(5+4) / (4.27 x 1.2) x 10^(4+4)
= 18.4525 x 10^9 / 5.124 x 10^8
= (18.4525 / 5.124) x 10^(9-8)
≈ 3.6 x 10^1
9514 1404 393
Answer:
(b) √65
Step-by-step explanation:
The modulus of a complex number is the root of the sum of the squares of the real and imaginary parts.
|1 -8i| = √(1² +(-8)²) = √(1+64) = √65
Before we get started, it is good to remember PEMDAS - the acronym that tells you the order to carry out equations.
P = parentheses
E = exponents
M = multiplication
D = division
A = addition
S = subtraction
Knowing this, we should start by doing the equations <em>within </em>each parentheses.

So we did the addition and subtraction pieces within each group leaving us with the above equation. Now let's multiply:

20 is the answer.
To make the equation easier so that you don't have to use fractions.
