Answer:
308[cos(45) + isin(45)]
Step-by-step explanation:
z1×z2:
Modulus: r1 × r2
= 7×44 = 308
Argument: theta1 + theta2
= -70 + 115 = 45
z1z2 = 308[cos(45) + isin(45)]
Or
z1z2 = 154sqrt(2) + (i)154sqrt(2)
sqrt: square root
Since you’re multiplying n^-6 and n^3, you can add the exponents: -6+3 = -3
n^-6 * n^3 = n^-3
If you need to finish without having a negative exponent in your answer, then remember a negative exponent means that factor is on the wrong side of the fraction.
n^-3 = n^-3 / 1 = 1/n^3
when the factor moves to the other side of the fraction, the side of the exponent changes.
Answer:
So the statement:
"The product of two irrational numbers is rational." is false.
Step-by-step explanation:
The product of two irrationals can be irrational or rational.
Example:
is irrational but when you multiply it to itself the output is rational.
Example:
are irrational and when you multiply them you get an irrational answer of 
.
So the statement:
"The product of two irrational numbers is rational." is false.
