Given:

The expressions are:

(5x-3y) and (8x+8y)

To find:

The difference of (5x-3y) and (8x+8y).

Solution:

Difference of (5x-3y) and (8x+8y) is written as:

Difference=(5x-3y)-(8x+8y)

On simplification, we get

Difference=5x-3y-8x-8y

Difference=(5x-8x)+(-3y-8y)

Difference=-3x-11y

Therefore, the difference of (5x-3y) and (8x+8y) is -3x-11y.

= 2.2 × 10⁸ beats

b)  Time = 6.00 years

[since 2 significant figure after decimal. answer will be give in 2 significant figure after decimal ]

time in minutes = 6.00 × 365 × 24 × 60

= 2.20 × 10⁸ beats

c) Time = 6.000 years

[since 3 significant figure after decimal. answer will be give in 3 significant figure after decimal ]

time in minutes = 6.000 × 365 × 24 × 60
