hai mate your answer

Step-by-step EXPLANATION:

Given,

We know, according to BINOMIAL theorem,

if Any number in the FORM of (1 + a)ⁿ , where a << 1

Then, (1 + a)ⁿ ≈ 1 + na

Now, (1003)⅓ = (1000 + 3)⅓

= (1000)⅓[ 1 + 3/1000]⅓

= 10[1 + 0.003]⅓

∵ 0.003 << 1

so, 10(1 + 0.003)⅓ = 10(1 + 0.003 × 1/3) = 10(1 + 0.001)

= 10 × 1.001

= 10.01

Hence,  = 10.01
