Question

Y = pq/p+q
p = 2.4×10^5

Answer 1

Explanation:

p=2.4×10^5.

q=3.7×10^5

pq = 2.4 * 10⁵ * 3.7 * 10⁵

= 2.4 * 3.7 *10⁽⁵⁺⁵⁾

= 8.88 * 10¹⁰

p + q = 2.4 * 10⁵ + 3.7 * 10⁵

= ( 2.4 + 3.7) * 10⁵

= 6.1 * 10⁵

`y = (pq)/(p+q)\\\\ = (8.88*10^(10))/(6.1*10^(5))\\\\= 1.46 * 10^(10-5)\\= 1.46 * 10^(5)`
