d) 4148
e) 4100

Answer 1

$\textbf {Hey there, here is the solution.}$

.............................................................................................

(78.95) ² - (43.35) ²

Apply a² - b² = (a + b) (a - b):

= (78.95 + 43.35) (78.95 - 43.35)

Evaluate each bracket:

= (122.3)(35.6)

Evaluate the answer:

= 4353.88

Answer 2

Answer-:

Given that,

(78.95)^2- (43.35)^2

We know that a^2-b^= (a+b) (a-b)

So here we put a = 78.95 and b= 43.35

(78.95)^2-(43.35)^2

=> (78.95+43.35) (78.95-43.35)

=> (122.3) (35.6)

=> 4353.88
