(15−4i)(6−3i)=a+bi In the equation above, a and b are real numbers and i=−1‾‾‾√. What is the value of a?

a=

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

step-by-step explanation:

b and c

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
