Part-A
1. State whether
10 will have terminating decimal expansion or a non-terminating
repeating decimal expansion.
OR
If the product of two numbers is 1080 and their HCF is 30, find their LCM.
2. Find the values of k for which the given equation has real and equal roots:
9x2 + 3x + 4 = 0
3. For what value of k, the following pair of linear equations has infinitely many solutions?​

Answer 1

Answer:

$a \: \times \: b \: = lcm \: \times hcf$

a x b = 30 x lcm

1080 = 30 x lcm

lcm = 1080/30

hope this help u
