Question

7+473
4. Find the product of 1+3 12 and 1 - 3 12. Is this product a rational or irrational?
3+V6
5. Find a and b if
M = a + b V3​

Answer 1

Step-by-step explanation:

(4) 1+(3)(12)(1)−(3)(12)

=1+(36)(1)−(3)(12)

=1+36−(3)(12)

=37−(3)(12)

=37−36

=1

1 stands for ¹/¹

that is a rational number

(5) Let's solve for a.

m=a+bv3

Step 1: Flip the equation.

bv3+a=m

Step 2: Add -bv^3 to both sides.

bv3+a+−bv3=m+−bv3

a=−bv3+m

Answer:

a=−bv3+m
