Question

solve the following by using identity 8.01 cube​

Answer 1

Answer:

Given : (8.1)²

Explanation:

Given that (8.1)²

using the identity

(a+b)² = a²+b²+2ab

(8.1)² = (8+ 0.1)²

then

(8+ 0.1)²

here a = 8 and b = 0.1

thus

(8+ 0.1)² = 8² + (0.1)² + 2(8) (0.1)

= 64 +1.6 + 0.01

= 65.61

hence , (8.1)² = 65.61
